Where IT comes from: Behind the scenes at Pure Storage’s European R&D centre

You’re a $2.8bn storage supplier with flash arrays at the core of your business. How do you do research and development (R&D), test new products, test customer workload issues, and test array products over years-long timescales for issues that only arise as software, network and application changes concatenate and interact?

Meanwhile, you are a global business with R&D and developer teams across time zones, all at work on ongoing monthly and quarterly updates, and incessant efforts to optimise storage controller software.

The base product is essentially the same, so effective collaboration and information sharing between teams spread across continents is key. But at the same time, you must also test regional customer-specific array configurations.

The Pure Storage solution is to divide responsibility between hardware and software, while also sharing specific R&D and testing capability between three sites.

There is Santa Clara in California, which is its global headquarters and handles hardware and software R&D and testing. There is also Bangalore in India, which only carries out software R&D and testing.

And there is Prague in Czechia, which recently opened its doors to the IT press. Here, we take a look at what goes on behind the scenes in R&D and product testing at Pure Storage (and its nearby array assembly operation).

Capabilities across the three centres are in many ways duplicated, which sounds counter-productive. But it’s not quite as simple as that, according to engineering vice-president and Pure’s Prague site leader Paul Melmon.

“Generally speaking, the same capabilities exist across all sites, except Santa Clara with its hardware development facilities,” he says.

“We try to make projects run autonomously and to minimise cross-time zone meetings,” says Melmon, adding that information can be shared globally in other ways, such as in Git repositories. 

“Lots of companies split projects into many pieces and distribute them,” says chief technology officer Rob Lee. “We choose significant parts of individual products and give them to individual sites, and have product managers for specific products sitting locally.”

“We give a lot of thought to what to centralise and what to not,” says Melmon. “We have rules of engagement that aim at communications that can minimise the number of meetings.”

R&D, testing and talent in Prague

As mentioned, Pure’s Prague site is dedicated to software research, development and testing. It runs thousands of ongoing and custom test routines on hundreds of racks of software. These are divided into “persistent” and “non-persistent” testing, says engineering manager Tom Healy.

Non-persistent is ephemeral. It tests for issues in specific customer deployment configurations, or the impact of updates on controller code.

Persistent testing is long-term. It can be very long-term, in fact, with racks in place with, for example, generation upon generation of Pure Storage FlashBlade file and object storage deployed.

“Sometimes things can take years to occur,” says Healy.

“Our testbeds include, for example, FlashBlade capacity that dates back to the first generation [2016], some virtualisation, and a Windows application platform. All of this will run for years, to follow the lifecycle of customer systems and to test for the effect of changes to software and hardware, and its stability,” says Healy.

“And, FlashBlade uses Ethernet, so we are checking what happens when changes happen in the workload, simulation of new cabling, media, hitting it with broadcast storms, simulating signal degradation, etc,” he adds. 

Meanwhile, at the Prague facility, hundreds of engineers work constantly on storage array software to meet ongoing monthly and quarterly updates. 

Pure’s Prague R&D facility has just celebrated its five-year anniversary. It is resident in the Amazon building (no relation) and others in the riverside Karlin district. There it employs 600 people – 50% Czech, 50% from elsewhere – with up to 50 nationalities on-site.

Prague was chosen as a European centre because of its proximity to so many of Pure’s customers, but also, says Melmon, because of the availability of talent. “It’s on a level with Silicon Valley,” he says, and its accessibility in terms of transport links, universities, graduates in computer science, cost of living and general likeability of the city.

Speaking of the River City complex in which Pure is located, Melmon describes it as having a “South of Market” feel, referring to the fashionable area of San Francisco that became a honeypot for startups in the 1990s. “It’s the place to be if you’re in tech and AI [artificial intelligence]. There are meetups in the evening. It’s the cool new place to be in Prague.”

But it’s not just a cool place to work and live. Melmon points to the 19.7% figure, which is the proportion of revenue Pure spends on R&D. 

Prague is the biggest Pure Storage R&D centre outside the US and has delivered about a third of its FlashArray product development. Meanwhile, FlashBlade//S was jointly designed and tested there, while key elements of the Pure Fusion workload management platform and its Pure1 AIOps were developed in the Czech capital. Meanwhile, 100% of Portworx Data Services and Pure’s disaster recovery as a service (DRaaS) offering came from there too.

That’s the result, with Prague as a key pillar in the three-site R&D and testing strategy of Pure Storage.

Nearby, also in Czechia, is one of its global assembly centres, which you can read about here.

It sure looks like Apple is getting ready to release a HomePod with a display

Another rumor suggests Apple’s long-rumored HomePod with a display is launching in 2025. This time, a paywalled report by DigiTimes (via MacRumors) says Tianma Microelectronics will supply the gadget’s 7-inch LCD panel. Taiwan’s Radiant will reportedly handle backlight module production, and BYD will assemble the device.

Rumors about this HomePod with a screen have been floating on the web for years now, especially with conflicting reports about Apple’s upcoming home robot.

Last year, tvOS 17.4 hinted at this device, and Bloomberg’s Mark Gurman said Apple was planning to combine the Apple TV, FaceTime, and HomePod in one system. The journalist said Cupertino also wanted to create a “HomePod with a screen that swivels like a robotic arm.” This HomePod with an iPad-like display could be released as soon as 2026.

In 2023, analyst Ming-Chi Kuo said Apple was readying a HomePod with a screen for the first half of 2024. While he eventually reframed his prediction to 2025, he believed it could feature a 7-inch display with Tianma manufacturing it. “The HomePod, which equips a panel, could enable tighter integration with Apple’s other hardware products, marking a significant shift in the company’s smart home strategy.”

Rumors say Apple has been working on several HomePod variants with screens. Two of them are a tabletop device with a robotic arm, and the other is an iPad-like product with a speaker combo and a built-in camera, something like an Amazon Echo Show.

In addition, a HomePod 3 is expected to be released as Apple’s smart home hub. Although reports suggest Apple Intelligence could play a big role in a smart speaker/display device, adding a better A17 Pro or M chip could greatly increase the price of a device most people aren’t willing to buy.

It seems that this product could be revealed in the third quarter of 2025, after the WWDC 2025 keynote. As always, BGR will monitor rumors and reports about this smart speaker and let you know if we learn more.

CCS cloud hosting deal with AWS under scrutiny as contract value soars by 89% after 15 months

The Crown Commercial Service’s (CCS) decision to increase its cloud hosting spend with Amazon Web Services (AWS) mid-contract by 89% is under scrutiny from procurement professionals.

The government’s procurement arm is overseeing the migration of workloads from the Government Digital Service’s now defunct Gov.uk platform-as-a-service (PaaS) offering to the AWS cloud.

This piece of work is covered by a £1.3m, 36-month contract CCS arranged with the public cloud giant in February 2023 through the G-Cloud 13 framework.

It has since emerged that CCS issued a Change Control Notice (CCN) that confirms the contract value increased by 89% to £2.5m in May 2024, despite deal value increases of that size not being strictly permitted under procurement rules.

“Following the migration…to AWS, there is a need to increase the contract value of the CCS Hosting contract to date for the increased costs incurred for these migrated services,” the CCN notice stated.

Under the terms of Regulation 72 of the Public Contracts Regulations 2015 (PCR15), contracts “may be modified without a new procurement procedure…provided that any increase in price does not exceed 50% of the value of the original contract”. 

On this basis, CCS is now being called on to explain why this contract was not retendered or subject to further competition, once it realised the original AWS contract would not cover the total cost of the work involved.

“The contract was awarded under G-Cloud 13, and is obviously governed by PCR15. There’s no argument with that,” said one public sector IT procurement expert, who spoke to Computer Weekly on condition of anonymity.

“But the CCS has not provided a plausible explanation for the uplift in contract value following the CCN, which clearly puts it in the threshold that requires further competition.”

Public procurement adviser Martin Medforth told Computer Weekly that Regulation 72 of PCR15 does permit public sector IT buyers to increase the original value of their contracts by more than 50% – just not all in one go.

“Regulation 72 is a funny one, in that it can be applied multiple times,” he said. “So, you can apply the 50% and then, if [the buyer] realises they still have a bit of work to do, they can apply the 50% again.”

It is not clear from the CCN notice if CCS did exercise its right to increase the size of its AWS deal multiple times, or if the 89% increase was pushed through regardless. 

Computer Weekly contacted CCS to query the change in deal size and what its response would be to claims the contract change is misaligned with the contents of PCR15.

In response to the request, a CCS spokesperson stated: “Crown Commercial Service follows procurement legislation, under the Public Contracts Regulations 2015, which ensures that all government contracts are awarded fairly and transparently. This contract was awarded using the G-Cloud 13 framework agreement.”

Nicky Stewart, senior adviser to the Open Cloud Coalition (OCC), which champions competition within the public cloud market, told Computer Weekly that it is important that high-profile, public sector organisations such as CCS demonstrate good practice when procuring cloud services.

“The OCC fully supports open and transparent procurement principles when it comes to cloud,” said Stewart. “This includes making legitimate opportunity available to all, including challenger cloud providers, and we hope that high-profile buying authorities such as the CCS will show leadership in this respect.”

Questioning the original deal size

The fact the deal size has required such a sizeable uplift after 15 months or so of work suggests CCS underestimated how much the migration would cost, continued Medforth. “Had I personally done this deal, I would have probably let this for ‘up to £5m’, to be on the safe side,” he said.

That is a sentiment shared by Owen Sayers, an enterprise architect with more than 20 years’ experience in delivering national policing systems, who told Computer Weekly that questions need to be asked about how CCS got its “sums so wrong” in the first instance where this contract is concerned.

“Having to almost double a £1.3m, three-year contract just over a third of the way into its lifecycle suggests that the original due diligence and understanding of the requirement was somewhat lacking,” he said.

Computer Weekly also contacted AWS for comment on this story, but the company declined.

AWS offers Hackney Council ‘minimum 22%’ discount on cloud services through OGVA 2.0

Hackney Council has committed to growing its annual usage of Amazon Web Services’ (AWS) cloud platform by 8% a year over the next three years to secure a “minimum 22%” discount on the public cloud giant’s services, Computer Weekly understands.

The local authority’s latest cloud hosting deal with AWS went live on 1 November 2024, after Hackney Council secured permission from the Cabinet Procurement and Insourcing Committee (CPIC) to re-sign the public cloud giant to host its core cloud services for another 36 months. The contract award notice for the deal confirms it has a maximum value of £3m.

Computer Weekly has received a copy of a 15-page document, created in July 2024, which details the reasons why the CPIC should recommend green-lighting a council proposal to award the three-year contract to AWS with a total value of £2.95m.

As detailed in the document, the council has been an AWS user since 2019, but use of its technology has accelerated at a “faster pace than was anticipated” in the wake of the ransomware attack Hackney Council suffered in October 2020.

“The cyber attack of 2020 demonstrated the importance of [moving to the cloud] as the services that had already migrated to the cloud were protected from the attack,” the document stated.

“Our investments in recovery [from the ransomware attack] have brought forward migration to the cloud… [with] almost all of the council’s systems now provided through the cloud.”

The council’s “accelerated transition to the cloud” has seen the value of its cloud contracts increase from just over £1m to approximately £2.85m, which included “one-off costs related to data recovery work” as a direct result of the 2020 cyber attack.

However, as detailed in the document, the council has been working to streamline its cloud estate by decommissioning services that are no longer being used, and ensuring the resources that remain in use are “right-sized”.

The document continued: “We have seen our cloud usage stabilise over the past year and are continuing to actively look for opportunities to cut the costs of running the estate, including reducing consumption-based usage costs and paying for known product usage in advance to secure discounts.”

On this point, the document states the council is set to benefit from the committed spend discount scheme the UK government has in place with AWS, known as the One Government Value Agreement (OGVA) 2.0, through this proposed deal.

“[This] gives the council access to discounted pricing subject to agreeing to contractual commitment value based on our spend over the previous 12-month period,” the document stated.

“This value has been calculated and the annual commitment for the contract will be £909,800 in the first year, £982,600 in the second and £1,061,100 in the third … the total contract value over the three-year term will be £2,953,500.”

Additionally, the OGVA 2.0 agreement will also allow the council to “further offset the value of the contract” with a minimum of 22% discount on AWS’s standard pricing model, which should bring the estimated “actual spend” for the three-year contract down to £2.3m.

“These costs and savings figures are based on our current projected spend and growth as required by the One Government Value Agreement stipulations,” the document stated.

“As part of the agreement we will be committed to an annual usage growth of 8% but we will in turn benefit from a minimum of 22% savings year-on-year on the standard pricing model for the resources we use.”

Computer Weekly asked Hackney Council to confirm if it was benefiting from the discount terms set out in the document now the contract has gone live, but a spokesperson for the local authority said: “The council is not in a position to confirm the terms of the agreement.”

Computer Weekly also contacted AWS to clarify if the 22% minimum discount and 8% usage commitment outlined in the document are typical of the discounts available to public sector buyers through OGVA 2.0. AWS, however, declined to comment.

The OGVA 2.0 agreement was quietly launched by AWS in December 2023, with government procurement chiefs at the Crown Commercial Service (CCS) claiming the agreement will deliver sizeable financial benefits to public sector IT buyers through the discounts it offers.

However, no details about the exact level of discount users will benefit from have previously been made public, as contract award notices for OGVA G-Cloud deals are typically heavily redacted.

On this point, details about an 18% baseline discount offered through the first iteration of the OGVA agreement only emerged after an unredacted contract award notice was published in error on the government’s Contract Finder website.  

Incidentally, preferential pricing schemes like OGVA are one of several areas the UK Competition and Markets Authority is looking into as part of its ongoing antitrust investigation focused on the UK cloud infrastructure market as it seeks to determine if the use of committed spend discounts could be harming the sector’s competitiveness.

Top 10 data and ethics stories of 2024

In 2024, Computer Weekly’s data and ethics coverage continued to focus on the various ethical issues associated with the development and deployment of data-driven systems, particularly artificial intelligence (AI).

This included reports on the copyright issues associated with generative AI (GenAI) tools, the environmental impacts of AI, the invasive tracking tools in place across the internet, and the ways in which autonomous weapons undermine human moral agency.

Other stories focused on the wider social implications of data-driven technologies, including the ways they are used to inflict violence on migrants, and how our use of technology prefigures certain political or social outcomes.

In an analysis published 14 January 2024, the IMF examined the potential impact of AI on the global labour market, noting that while it has the potential to “jumpstart productivity, boost global growth and raise incomes around the world”, it could just as easily “replace jobs and deepen inequality”; and will “likely worsen overall inequality” if policymakers do not proactively work to prevent the technology from stoking social tensions.

The IMF said that, unlike labour income inequality, which can decrease in certain scenarios where AI’s displacing effect lowers everyone’s incomes, capital income and wealth inequality “always increase” with greater AI adoption, both nationally and globally.

“The main reason for the increase in capital income and wealth inequality is that AI leads to labour displacement and an increase in the demand for AI capital, increasing capital returns and asset holdings’ value,” it said.

“Since in the model, as in the data, high income workers hold a large share of assets, they benefit more from the rise in capital returns. As a result, in all scenarios, independent of the impact on labour income, the total income of top earners increases because of capital income gains.”

In January, GenAI company Anthropic claimed to a US court that using copyrighted content in large language model (LLM) training data counts as “fair use”, and that “today’s general-purpose AI tools simply could not exist” if AI companies had to pay licences for the material.

Anthropic made the claim after, a host of music publishers including Concord, Universal Music Group and ABKCO initiated legal action against the Amazon- and Google-backed firm in October 2023, demanding potentially millions in damages for the allegedly “systematic and widespread infringement of their copyrighted song lyrics”.

However, in a submission to the US Copyright Office on 30 October (which was completely separate from the case), Anthropic said that the training of its AI model Claude “qualifies as a quintessentially lawful use of materials”, arguing that, “to the extent copyrighted works are used in training  data, it is for analysis (of statistical relationships between words and concepts) that is unrelated  to any expressive purpose of the work”.

On the potential of a licensing regime for LLM’s ingestion of copyrighted content, Anthropic argued that always requiring licences would be inappropriate, as it would lock up access to the vast majority of works and benefit “only the most highly resourced entities” that are able to pay their way into compliance.

In a 40-page document submitted to the court on 16 January 2024 (responding specifically to a “preliminary injunction request” filed by the music publishers), Anthropic took the same argument further, claiming “it would not be possible to amass sufficient content to train an LLM like Claude in arm’s-length licensing transactions, at any price”.

It added that Anthropic is not alone in using data “broadly assembled from the publicly available internet”, and that “in practice, there is no other way to amass a training corpus with the scale and diversity necessary to train a complex LLM with a broad understanding of human language and the world in general”. 

Anthropic further claimed that the scale of the datasets required to train LLMs is simply too large to for an effective licensing regime to operate: “One could not enter licensing transactions with enough rights owners to cover the billions of texts necessary to yield the trillions of tokens that general-purpose LLMs require for proper training. If licences were required to train LLMs on copyrighted content, today’s general-purpose AI tools simply could not exist.”

Computer Weekly spoke to members of the Migrants Rights Network (MRN) and Anti-Raids Network (ARN) about how the data sharing between public and private bodies for the purposes of carrying out immigration raids helps to prop up the UK’s hostile environment by instilling an atmosphere of fear and deterring migrants from accessing public services.

Published in the wake of the new Labour government announcing a “major surge in immigration enforcement and returns activity”, including increased detentions and deportations, a report by the MRN details how UK Immigration Enforcement uses data from the public, police, government departments, local authorities and others to facilitate raids.

Julia Tinsley-Kent, head of policy and communications at the MRN and one of the report’s authors, said the data sharing in place – coupled with government rhetoric about strong enforcement – essentially leads to people “self-policing because they’re so scared of all the ways that you can get tripped up” within the hostile environment.

She added this is particularly “insidious” in the context of data sharing from institutions that are supposedly there to help people, such as education or healthcare bodies.

As part of the hostile environment policies, the MRN, the ARN and others have long argued that the function of raids goes much deeper than mere social exclusion, and also works to disrupt the lives of migrants, their families, businesses and communities, as well as to impose a form of terror that produces heightened fear, insecurity and isolation.

At the very end of April, military technology experts gathered in Vienna for a conference on the development and use of autonomous weapons systems (AWS), where they warned about the detrimental psychological effects of AI-powered weapons.

Specific concerns raised by experts throughout the conference included the potential for dehumanisation when people on the receiving end of lethal force are reduced to data points and numbers on a screen; the risk of discrimination during target selection due to biases in the programming or criteria used; as well as the emotional and psychological detachment of operators from the human consequences of their actions.

Speakers also touched on whether there can ever be meaningful human control over AWS, due to the combination of automation bias and how such weapons increase the velocity of warfare beyond human cognition.

The second global AI summit in Seoul, South Korea saw dozens of governments and companies double down on their commitments to safely and inclusively develop the technology, but questions remained about who exactly is being included and which risks are given priority. 

The attendees and experts Computer Weekly spoke with said while the summit ended with some concrete outcomes that can be taken forward before the AI Action Summit due to take place in France in early 2025, there are still a number of areas where further movement is urgently needed.

In particular, they stressed the need for mandatory AI safety commitments from companies; socio-technical evaluations of systems that take into account how they interact with people and institutions in real-world situations; and wider participation from the public, workers and others affected by AI-powered systems.

However, they also said it is “early days yet” and highlighted the importance of the AI Safety Summit events in creating open dialogue between countries and setting the foundation for catalysing future action.

Over the course of the two-day AI Seoul Summit, a number of agreements and pledges were signed by the governments and companies in attendance.

For governments, this includes the European Union (EU) and a group of 10 countries signing the Seoul Declaration, which builds on the Bletchley Deceleration signed six months ago by 28 governments and the EU at the UK’s inaugural AI Safety Summit. It also includes the Seoul Statement of Intent Toward International Cooperation on AI Safety Science, which will see publicly backed research institutes come together to ensure “complementarity and interoperability” between their technical work and general approaches to AI safety.

The Seoul Declaration in particular affirmed “the importance of active multi-stakeholder collaboration” in this area and committed the governments involved to “actively” include a wide range of stakeholders in AI-related discussions.

A larger group of more than two dozen governments also committed to developing shared risk thresholds for frontier AI models to limit their harmful impacts in the Seoul Ministerial Statement, which highlighted the need for effective safeguards and interoperable AI safety testing regimes between countries.

The agreements and pledges made by companies include 16 AI global firms signing the Frontier AI Safety Commitments, which is a specific voluntary set of measures for how they will safely develop the technology, and 14 firms signing the Seoul AI Business Pledge, which is a similar set of commitments made by a mixture of South Korean and international tech firms to approach AI development responsibly.

One of the key voluntary commitments made by the AI companies was not to develop or deploy AI systems if the risks cannot be sufficiently mitigated. However, in the wake of the summit, a group of current and former workers from OpenAI, Anthropic and DeepMind – the first two of which signed the safety commitments in Seoul – said these firms cannot be trusted to voluntarily share information about their systems capabilities and risks with governments or civil society.

 Dozens of university, charity and policing websites designed to help people get support for serious issues such as sexual abuse, addiction or mental health are inadvertently collecting and sharing site visitors’ sensitive data with advertisers.  

A variety of tracking tools embedded on these sites – including Meta Pixel and Google Analytics – mean that when a person visits them seeking help, their sensitive data is collected and shared with companies like Google and Meta, which may become aware that a person is looking to use support services before those services can even offer help.

According to privacy experts attempting to raise awareness of the issue, the use of such tracking tools means people’s information is being shared inadvertently with these advertisers, as soon as they enter the sites in many cases because analytics tags begin collecting personal data before users have interacted with the cookie banner.

Depending on the configuration of the analytics in place, the data collected could include information about the site visitor’s age, location, browser, device, operating system and behaviours online.

While even more data is shared with advertisers if users consent to cookies, experts told Computer Weekly the sites do not provide an adequate explanation of how their information will be stored and used by programmatic advertisers.

They further warned the issue is “endemic” due a widespread lack of awareness about how tracking technologies like cookies work, as well as the potential harms associated with allowing advertisers inadvertent access to such sensitive information.

Computer Weekly spoke to author and documentary director Thomas Dekeyser about Clodo, a clandestine group of French IT workers who spent the early 1980s sabotaging technological infrastructure, which was used as the jumping off point for a wider conversation about the politics of techno-refusal.

Dekeyser says a major motivation for writing his upcoming book on the subject is that people refusing technology – whether that be the Luddites, Clodo or any other radical formation – are “all too often reduced to the figure of the primitivist, the romantic, or the person who wants to go back in time, and it’s seen as a kind of anti-modernist position to take”.

Noting that ‘technophobe’ or ‘Luddite’ have long been used as pejorative insults for those who oppose the use and control of technology by narrow capitalist interests, Dekeyser outlined the diverse range of historical subjects and their heterogenous motivations for refusal: “I want to push against these terms and what they imply.”

For Dekeyser, the history of technology is necessarily the history of its refusal. From the Ancient Greek inventor Archimedes – who Dekeyser says can be described as the first “machine breaker” due to his tendency to destroy his own inventions – to the early mercantilist states of Europe backing their guild members’ acts of sabotage against new labour devices, the social-technical nature of technology means it has always been a terrain of political struggle.

Hundreds of workers on Amazon’s Mechanical Turk (MTurk) platform were left unable to work after mass account suspensions caused by a suspected glitch in the e-commerce giant’s payments system.

Beginning on 16 May 2024, a number of US-based Mechanical Turk workers began receiving account suspension forms from Amazon, locking them out of their accounts and preventing them from completing more work on the crowdsourcing platform.

Owned and operated by Amazon, Mechanical Turk allows businesses, or “requesters”, to outsource various processes to a “distributed workforce”, who then complete tasks virtually from wherever they are based in the world, including data annotation, surveys, content moderation and AI training.

According to those Computer Weekly spoke with, the suspensions were purportedly tied to issues with the workers’ Amazon Payment accounts, an online payments processing service that allows them to both receive wages and make purchases from Amazon. The issue affected hundreds of workers.

MTurk workers from advocacy organisation Turkopticon outlined how such situations are an on-going issue that workers have to deal with, and detailed Amazon’s poor track record on the issue.

Refugee lawyer and author Petra Molnar spoke to Computer Weekly about the extreme violence people on the move face at borders across the world, and how increasingly hostile anti-immigrant politics is being enabled and reinforced by a ‘lucrative panopticon’ of surveillance technologies.

She noted how – because of the vast array of surveillance technologies now deployed against people on the move – entire border-crossing regions have been transformed into literal graveyards, while people are resorting to burning off their fingertips to avoid invasive biometric surveillance; hiding in dangerous terrain to evade pushbacks or being placed in refugee camps with dire living conditions; and living homeless because algorithms shielded from public scrutiny are refusing them immigration status in the countries they’ve sought safety in.

Molnar described how lethal border situations are enabled by a mixture of increasingly hostile anti-immigrant politics and sophisticated surveillance technologies, which combine to create a deadly feedback loop for those simply seeking a better life.

She also discussed the “inherently racist and discriminatory” nature of borders, and how the technologies deployed in border spaces are extremely difficult, if not impossible, to divorce from the underlying logic of exclusion that defines them.

The potential of AI to help companies measure and optimise their sustainability efforts could be outweighed by the huge environmental impacts of the technology itself.

On the positive side, speakers at the AI Summit London outlined, for example, how the data analysis capabilities of AI can assist companies with decarbonisation and other environmental initiatives by capturing, connecting and mapping currently disparate data sets; automatically pin point harmful emissions to specific sites in supply chains; as well as predict and manage the demand and supply of energy in specific areas.

They also said it could help companies better manage their Scope 3 emissions (which refers to indirect greenhouse gas emissions that occur outside of a company’s operations, but that are still a result of their activities) by linking up data sources and making them more legible.

However, despite the potential sustainability benefits of AI, speakers were clear that the technology itself is having huge environmental impacts around the world, and that AI itself will come to be a major part of many organisations Scope 3 emissions.

One speaker noted that if the rate of AI usage continues on its current trajectory without any form of intervention, then half of the world’s total energy supply will be used on AI by 2040; while another pointed out that, at a time when billions of people are struggling with access to water, AI-providing companies are using huge amounts of water to cool their datacentres.

They added AI in this context could help build in circularity to the operation, and that it was also key for people in the tech sector to “internalise” thinking about the socio-economic and environmental impacts of AI, so that it is thought about from a much earlier stage in a system’s lifecycle.

AWS on using GenAI to speed up legacy VMware and Microsoft datacentre migrations

Amazon Web Services (AWS) has set out how its investments in artificial intelligence (AI) chips and software are saving customers money and helping them migrate their legacy Windows and VMware workloads off-premise much quicker.

AWS CEO Matt Garman used the opening keynote at the public cloud giant’s Re:Invent customer and partner conference in Las Vegas, which is the first he has delivered since taking over the company reins in June 2024, to talk up the potential for generative AI (GenAI) to digitally transform the way that businesses operate. He also talked at length about the work that goes into ensuring the AWS cloud infrastructure is equipped to cope with the growing demand from its customers for the compute power they need to run AI and GenAI workloads.

As previously reported by Computer Weekly, the demand for GenAI workloads from its customers was recently cited as the reason for a “significant re-acceleration” in AWS’s annual growth rate, with the company reporting a 19.1% year-on-year uptick in revenue during its third-quarter results.  

Garman touched on Amazon’s 14-year-long collaboration with Nvidia, which he said has enabled it to roll out a succession of increasingly more powerful graphics processing unit (GPU) instances based on the latter’s technology so it can keep pace with its customers’ AI demands.

The company has also doubled down on the creation of its own AI silicon – namely its family of Tranium chips – to support a wider range of instances that are designed to improve the cost performance of running compute-intensive workloads. To this point, Garman used the keynote to announce that the second generation of Tranium instances had now become generally available, claiming the latest iteration can deliver “30-40%” better price performance than “current GPU-powered instances”.

This is based on feedback from early adopters of the technology, with Garman naming Adobe as among the customers who have seen some “promising” early wins with the technology.

Another is AI-focused software engineering startup Poolside, who has reportedly committed to training all future versions of their large frontier model on Tranium 2. The company is also anticipating the move will generate savings in the region of 40%. “Databricks is one of the largest data and AI companies in the world,” he said. “[It] plans to use Trainium 2 to deliver better results and [to] lower the total cost of ownership for our joint customers by up to 30%.” 

Opening up about Amazon’s use of GenAI

The conversation later moved on to how GenAI is also changing the way that AWS operates, with particular focus on how its own offerings are helping to speed up the time it takes to refactor legacy, on-premise workloads and ready them for migration to the public cloud.

Central to this bit of the discussion was Amazon Q, which is the company’s generative AI chatbot assistant that is designed for in-house use by software developers, business analysts and contact centre employees to make the work they do more efficient.

The migration of customer workloads out of private datacentres and into the public cloud is a process that fuelled the company’s growth for a decade or more after its inception in 2006.

However, despite the company previously acknowledging that a large proportion of enterprise workloads remain on-premise, it was an area that was markedly less talked about during the keynote, until Garman flagged how Amazon Q can assist with this task.

“Our goal at AWS is to help every builder be able to innovate, [and] we want to free you from the undifferentiated heavy lifting to really focus on those creative things that make your building unique … [and] generative AI is a huge accelerator of this capability,” he said.

As an example, he talked about how Amazon Q Developer, an iteration of the chatbot specifically designed to help developers speed up their CodeDeploy processes, is helping customers deploy faster, more secure and better-quality software updates.

Garman then went onto announce several new features that were being added to Amazon Q Developer that will generate unit tests, documentation and code reviews on behalf of developers, so they can spend more time each day writing code than dealing with the admin associated with it.

Addressing the legacy

The software is also reducing the amount of time they have to spend managing legacy applications, it is claimed.

“One of [the software’s] most powerful capabilities we already have is [its ability to] automate Java version upgrades,” said Garman. “What it can do is transform a Java application from an old version of Java to a new version in a fraction of the time it would take to do manually. This is work that no developer loves to do, but is critically important.”

According to Garman, integrating this capability into Amazon’s own internal systems saw it “migrate literally tens of thousands of production applications” to Java 17 in a “small fraction of the time” it would typically take. “The estimate from our teams is this saved us 4,500 developer years … [and] this is a mind-blowing amount of time saved, and because we’re now running on modern Java, we can use less hardware, too. So, we saved $260m a year through this process.”

Java upgrades are one thing, but – in Garman’s opinion – a migration that a lot of enterprises want assistance with is moving from Windows to Linux. And this is something AWS can assist with now through the preview release of a new version of Amazon Q Developer.

“Customers love an easy button to get off of Windows,” he said. “They’re tired of constant security issues, the constant packing or patching, all the scalability challenges that they have to deal with, and they definitely hate the onerous licensing costs.

“But we do recognise today that this is hard. Actually, modernising away from Windows is not easy, [but] with Q Developer, modernising windows just got a lot easier … [as it allows you] to transform .Net applications that are running on Windows to Linux in a fraction of the time.”

Signature IT

As an example, Garman flagged digital transactions, signing software company Signature IT, and the work it has done to modernise its legacy .Net applications and migrate them from Windows to Linux. “It was a project they estimated was going to take six to eight months, [and] they actually completed it in just a few days,” he said. “That is a game-changing amount of time.”

But it’s not just Windows workloads that enterprises are having a hard time modernising. “Windows is not the only legacy platform in the datacentre that is slowing down all your modernisation efforts … oftentimes it is VMware workloads that customers would really love to modernise to cloud-native services,” said Garman.

“VMware is deeply entrenched in many datacentres, and has been for a really long time. And what happens is … because it’s been there for a long time, there ends up [being] this kind of spaghetti mess of interconnected applications.”

“[So] really the hardest part about modernising is finding out what are the dependencies of those applications,” he said. “And the migrations are error-prone, because it’s hard to understand if you move something, if it is going to break something else. And again, of course, licensing is expensive.”

To assist with this, Q Developer also has capabilities that will allow VMware-based datacentre workloads to be reconfigured to become cloud-native, with the system able to identify the dependencies and create a migration plan for the user.

“[This] really reduces a ton of the migration time, and significantly it reduces [the organisation’s] risk,” said Garman. “It also launches agents that can convert on-premise VMware network configurations into modern AWS equivalents. This takes what used to be months and months of work into hours to weeks.”

The next complex datacentre migration project the company is looking to simplify for enterprises, with the help of Amazon Q, concerns mainframes, which Garman described as “by far the most difficult to migrate to the cloud”.

“When you talk to customers, just the effort of trying to analyse, document and plan mainframe modernisation is often too much, [and] people give up [because] it’s too hard. Turns out, Q can help with this, too,” he said.

The software has a number of agents in it that are able to do mainframe code analysis, refactor applications and create documentation in real time for legacy COBOL code so enterprises can fill in any knowledge gaps about what it might do.

“Most customers will tell you their mainframe migration will probably take three to five years … but planning a project for three to five years is nearly impossible,” said Garman. “A lot of the time, they just don’t get done.”

And while it’s beyond the capabilities of Amazon Q to make mainframe migrations a “one-click” job right now, he said early testing suggests the software could significantly accelerate the pace of these projects.

“We think Q can actually turn what was going to be a multi-year effort into a multi quarter effort, cutting by more than 50% the time to migrate mainframes,” said Garman. “If you can take a multi-year effort and bring it down to a couple of quarters, that’s something that people can really get their heads around. And customers are incredibly excited about this.”

Storage technology explained: Flash vs HDD

The past 12 months saw flash storage nudge into areas from which it had hitherto been absent. In particular, this was because of the availability of denser – and therefore cheaper per-gigabyte (GB) – quad-level cell (QLC) flash storage into array markets and use cases that were once considered nearline.

Alongside this, we saw the price-per-GB of flash drop towards the level of spinning disk hard disk drives (HDDs) then rebound rapidly as memory manufacturers chased profitability. Meanwhile, the keenest of flash storage advocates predicted the demise of the hard drive and the imminent victory of the all-flash datacentre.

In this article, we define enterprise flash storage, look into its QLC and triple-level cell (TLC) variants, the benefits of non-volatile memory express (NVMe) flash, and examine the pros and cons of flash versus HDD in terms of cost, performance, flash in the cloud, and the likelihood (or otherwise) of the all-flash datacentre.

What is enterprise flash storage?

Enterprise flash storage refers to systems that comprise multiple flash drives housed in datacentre rack-mounted array form factor products.

In enterprise flash storage arrays, the capacity of many drives is aggregated, with access to storage media governed by controller hardware.

The controller is compute that powers the intelligence needed to handle input/output (I/O) from hosts to the storage, decision-making over allocation of data to media, but also in flash arrays to carry out maintenance tasks such as wear levelling, garbage collection, and so on.

Enterprise flash storage array capacities run from tens of terabytes (TB) to many petabytes (PB). As with HDD-based arrays, access to storage can be block (for performance-hungry database use cases, for example), file (for general use and unstructured data) or object (for unstructured data also).

What is QLC flash storage?

QLC is the latest generation of flash storage media. QLC stands for quad-level cell. That means that every cell in the flash chip can store four bits of data using 16 states.

That means it can store more data in the same space than TLC flash, which is also widely available. Previously widely available were single-level cell (SLC) flash and multi-level cell (MLC, meaning two states), but these have been largely superseded now.

At the start of 2024, most enterprise storage arrays are built with TLC drives for general-purpose and mission-critical use cases. But QLC has edged into the mainstream and gained traction for unstructured data workloads, in particular with key enterprise storage array makers adding QLC-based products in the past year or so.

As manufacturers increase the number of possible states per cell, storage density increases and the cost of storage per GB decreases. But, as storage density increases in terms of cell capacity, issues can arise that can limit the endurance of flash media.

What is NVMe flash?

Non-volatile memory express (NVMe) is a protocol developed especially for use with flash storage. Prior to NVMe, flash drives used transport protocols that originated during the HDD era, namely Serial Advanced Technology Attachment (SATA) and Serial-Attached SCSI (SAS). In fact, these are still in use and arrays that use drives with such connectivity (2.5in and 3.5in form factor) are sold by the big storage suppliers.

But NVMe is at the forefront now for flash drive performance. NVMe’s key innovation was to optimise queues and buffers for use with flash, which improved performance many times over.

As a follow-on, suppliers then developed ways of allowing NVMe connectivity across physically more distant connections across the datacentre. Such NVMe-over-fabrics technologies include the ability to carry NVMe via Ethernet, Infiniband, TCP, RDMA (ie, memory-to-memory connectivity) and more.

What is HDD?

Hard disk drives (HDDs) that rely on magnetic read/write heads and mechanically spinning disks have been around for decades, with flash a competitor that has emerged in the past 10 years or so.

As with flash, HDDs can be aggregated into datacentre rack-mounted array products and the capacity of multiple drives pooled for enterprise users. In fact, HDD-based arrays long preceded enterprise flash arrays and are still widely used.  

What’s the difference in performance between flash and HDD?

When we look at flash versus disk, the key thing that stands out is that flash is fast – many times faster than spinning disk HDD.

Flash drives offer lower latency, with access times down to low milliseconds, or even microseconds, compared with the multiple milliseconds of spinning disk, particularly for reads. That means enterprise flash can also offer vastly more input/output operations per second (IOPS) when aggregated into a storage array.

In throughput terms, flash offers gigabit-per-second (Gbps) rates four or five times quicker than HDD.

Such rapidity has been the key draw for enterprise flash storage and is a result of the lack of moving parts. With spinning platters, HDD is limited by physics in ways that solid-state storage is not.

In terms of capacities, HDD is available in up to around 22TB units. And while some flash drives have been marketed that run to 60-plus terabytes, they generally come in smaller sizes, but part of that is because of cost. 

What’s the cost difference between flash and HDD?

In terms of per-GB cost at drive level, flash costs more than spinning disk.

Flash prices spiked significantly in late 2023 and the early months of 2024 as manufacturers throttled back production in an effort to raise prices and achieve profitability.

Solid-state drive (SSD) prices per gigabyte reached an average of $0.095/GB by April 2024, which was a rise of 26.67% since autumn 2023.

But, flash drive prices then fell steadily over the first three quarters of 2024 to an average of $0.085 per gigabyte (GB) in September 2024.

In October 2023, flash had averaged $0.075/GB while HDD averaged $0.05/GB for SAS and $0.035/GB for SATA drives.

Average spinning disk (SAS and SATA) hard drive prices held steady during the six months to September 2024 at $0.039 per gigabyte. That figure was $0.041/GB in early April.

For a customer that planned to deploy 20TB of flash, based on those prices, it would have cost $1,500 in October 2023, $1,900 in April 2024, and $1,700 in September 2024. That compares to the equivalent for spinning disk of $850 in October 2023 and $780 in September 2024.

Will flash kill HDD? How much longer for HDD?

In particular, Pure Storage has declared HDDs will be dead by 2028, with its flash products the chief agent in the cull, and all owing to its ability to aggregate much more flash capacity on its proprietary modules than occurs on commodity flash drives.

With flash module sizes of up to 300TB by 2026 promised by Pure, it contends that spinning disk will be commercially unviable.

Meanwhile, companies such as Panasas, which specialises in storage for unstructured data, point to hyperscaler datacentres’ overwhelming use of spinning disk in ratios up to 90/10 against flash. Panasas argues that there’s still a five-times differential between the lowest-cost flash and HDD, and that for most, something like the hyperscaler solution is optimal.  

When can you use flash and HDD in the cloud?

Enterprise users can also specify flash storage and spinning disk in the cloud. It is more likely in most cases that cloud storage will be specified by performance and cost criteria, in which case the customer may never know what media underlies it.

But it is possible also to specify flash storage in the cloud and the three largest hyperscalers – Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform (GCP) – have solid-state storage options that mix cost, capacity and performance. 

The hyperscalers all offer flash storage to support compute with service levels based on capacity and IOPS per volume that range from general-purpose to premium levels aimed at specific workloads (eg, SQL, Oracle, SAP Hana) and environments (eg, Windows, Lustre, MacOS).

There are also options aimed at flash for file storage and flash storage from named suppliers, such as Azure’s NetApp Files.

What is the all-flash datacentre?

For about a decade, the idea of the all-flash datacentre has been discussed. The all-flash datacentre replaces HDD and other media such as tape with flash storage.

Driving it is the continued decrease in the cost of flash storage – as with QLC flash – but also the advantages of flash in terms of rapid access. The latter becomes more relevant as customers want to run analytics on bigger subsets of their data.

So, for example, where backups may previously have been held on nearline media such as slower HDDs, advocates of flash for such use cases point to the ability to run artificial intelligence (AI) on large customer datasets and to gain value therefrom.

Also, with backups as an example, the idea of being able to recover quickly from flash media in case of a ransomware attack is another use case touted by all-flash datacentre boosters. 

When will the all-flash datacentre arrive?

While enthusiastic suppliers of flash storage such as Pure talk down the obstacles to the all-flash datacentre, analysts point to the spread of (especially QLC) flash into secondary workloads but not necessarily all use cases, with spinning disk likely to retain its usefulness for some time for some datasets.

Meanwhile, HDD suppliers such as Toshiba say around 85% of all data is still on spinning disk. That fact, it says, is not likely to change rapidly, not least because the flash capacity to replace it doesn’t exist.

AWS widening scope of MFA programme after early success

Amazon Web Services (AWS) is to widen the scope of a mandatory multi-factor authentication (MFA) programme it introduced earlier this year, after seeing strong uptake among customers and a slump in password-related phishing attacks.

The cloud giant made MFA compulsory for management account root users in the AWS Management Console beginning in May 2024, starting with its largest accounts. In June, it added support for FIDO2 passkeys as an MFA method to give users more options, and expanded the original requirement to include root users in standalone accounts, too.

According to AWS principal product manager of account protection Arynn Crow, over 750,000 root users have enabled MFA since April, with customer registration rates more than doubling since the addition of FIDO2 passkeys to the mix. She claimed the policy change had prevented “greater than 99%” of password-related attacks.

“At AWS, we’ve built our services with secure-by-design principles from day one, including features that set a high bar for our customers’ default security posture,” said Crow. “Strong authentication is a foundational component in overall account security, and the use of MFA is one of the simplest and most effective ways to help prevent unauthorised individuals from gaining access to systems or data.”

Based on this early success, AWS will now be expanding MFA requirements to member accounts in AWS organisations from Spring 2025.

“Customers who have not enabled central management of root access will be required to register MFA for their AWS Organizations member account root users in order to access the AWS Management Console,” said Crow.

“As with our previous expansions to management and standalone accounts, we will roll this change out gradually and notify individual customers who are required to take action in advance, to help customers adhere to the new requirements while minimising impact to their day-to-day operations.”

No more passwords anymore

On the back of its early successes with an MFA mandate, Crow said AWS was keen to do more to shore up security for its customers, and had recognised another opportunity to try to eliminate unnecessary passwords for good.

She said that on top of the run-of-the-mill security issues seen with standard passwords, attempting to secure password-based authentication was introducing too much operational overhead for AWS customers, especially those operating at scale or subject to regulatory requirements to rotate their credentials frequently.

As such, AWS has now launched a new capability to centrally manage root access for accounts managed in AWS Organizations, enabling them to cut down on the number of passwords they need to manage while still keeping control over the use of root principals.

Crow explained that customers can now turn on centralised root access with a quick configuration change – either in the identity and access management console or the AWS command line interface – and then remove the long-term credentials of member account root users.

“This will improve the security posture of our customers while simultaneously reducing their operational effort,” she concluded.

Nationwide Building Society backs HPE GreenLake for hybrid cloud push

Nationwide Building Society is drawing on HPE’s private cloud capabilities to help deliver on the next phase of its multi-year hybrid cloud strategy.

The company, which has more than 17 million customers in the UK and employs 18,000 people, is in midst of a hybrid cloud-focused digital transformation project, geared towards improving the online experience for its customers.

As previously reported by Computer Weekly, this work, which began in 2018, has seen the firm use public cloud technologies, such as those offered by Amazon Web Services, and embrace the use of DevOps-style software development methodologies within its teams.

The project has also seen Nationwide adopt different cloud technologies based on what is best for that particular type of data or workload, which is why the company is now adding the HPE Greenlake private cloud setup to its supplier mix too.

“Nationwide’s hybrid cloud strategy is vital to our ability to compete and means we can continue to meet the needs and expectations of our customers – HPE GreenLake cloud is a core component of our hybrid cloud strategy,” said Paul Walsh, director of infrastructure and service delivery at Nationwide.

“With them, we’re building a cloud platform that will further improve our resilience and agility, enabling us to provide even better levels of service and deliver new capabilities to our developers faster than ever before.”

Specifically, Nationwide will use HPE GreenLake management services to automate and orchestrate its infrastructure management workloads and deliver infrastructure-as-code, the company said.

“This [will] enable [Nationwide] to focus on innovation, value-add activities and gain better control over application builds and security,” said the company, in a statement. “Faster release cycles will accelerate the time to market, providing consistent customer experiences across all digital platforms.”

The HPE GreenLake cloud setup will also provide Nationwide with an overview of its energy consumption and emissions, so that it can take proactive steps to reduce its environmental footprint, the company added.

Matt Harris, senior vice-president and managing director for the UK, Ireland, Middle East and Africa at HPE, said the complexities of the deployment highlight why taking a public cloud-only approach would not work for a company like Nationwide.

“Nationwide’s modernisation journey showcases the effectiveness of HPE GreenLake cloud, with the storied institution transitioning from complex, legacy technology to a modern, future-proofed hybrid cloud operating model where a one-size-fits-all public cloud could never be the only answer,” said Harris.

Nationwide is not the only financial services company tapping into HPE GreenLake to deliver on its hybrid cloud strategy, as Barclays Bank also set out plans in September 2024 to ramp up its use of the technology for that purpose.

AMD’s Ryzen chips appear to be wiping the floor with Intel – but the best-selling CPUs right now might surprise you

  • Intel’s top-selling CPU is a lowly number 13 in Amazon rankings
  • Team Blue is doing better in the Newegg CPU chart, but still not well
  • This may reflect fallout from Intel’s recent fumbles with chip instability and the rocky Arrow Lake launch

AMD is totally cleaning up in the world of desktop processors, with Intel lagging way behind its rival now, at least going by Amazon’s rankings of the bestselling CPUs.

As you may be aware, Amazon keeps track of the bestsellers across its entire range of tech (and other) products, and the top processor list is currently dominated by AMD, with Team Red now holding the entire top 10.

In fact, the first Intel CPU you’ll see is the Intel Core i5-13600KF at number 13, so the top 12 processors are from AMD (at the time of writing, anyway). Granted, Intel does have numbers 14, 15, 17, and 18 as well, notably with older CPUs from the 13th-gen and 14th-gen ranges, with no Core Ultra 200S (Arrow Lake) chips to be seen in the top 20 – or indeed in the top 100.

Are those chips simply too fresh to the market, then? Well, AMD’s Ryzen 9800X3D is also very new on the scene and is ranked at the number four spot, in fact, it’s been so popular that at the time of writing it’s sold out of stock.

What are AMD’s top chips by sales, then? At number one we have the AMD Ryzen 5700X, the mainstay from two generations ago which is still selling strongly, followed by its more affordable sibling, the 5600X.

The AMD Ryzen 7800X3D is in third place, followed by the 9800X3D as mentioned, and then the Ryzen 7600X is in fifth. It makes sense to see the 7800X3D in a strong position; it’s now the cheaper alternative to the next-gen 9800X3D, while remaining a strong choice of CPU for serious PC gamers.

Analysis: Processing advantage AMD

This represents a very clear picture of how AMD has pulled ahead in the CPU arena, albeit it is just one retailer – though a huge retail player, of course.

If you look at Newegg, which also keeps a regularly updated CPU ranking, this isn’t quite as heavily weighted towards AMD, but Team Red is clearly winning. In this case, Intel does have chips at numbers five through to eight, and 14, plus 20, but the rest of the top 20 is entirely AMD (again, that’s correct at the time of writing, though the processors may have shuffled around a bit by the time you’re reading this).

It’s much the same story as Amazon with the bestselling Ryzen chips, though the top seller is actually the Ryzen 9800X3D in this case (even though it has sold out – stock is still a big issue for would-be buyers), followed by the Ryzen 7600X (with a nice discount as you might guess). For Intel, the 14700K and 14900K are the top offerings – you won’t find an Arrow Lake CPU until number 39, where the flagship 285K currently resides.

Are we particularly surprised at this development? Well, not really, although the grip AMD has on the market at Amazon is pretty eye-opening. But given recent history in the world of CPUs, with Intel having a nightmarish time with its 14th-gen and 13th-gen silicon suffering serious instability problems, and Arrow Lake having a wobbly launch too, it’s pretty much a given that AMD is going to capitalize on these missteps.

Even if Ryzen 9000 also received a rather lukewarm reception, albeit the Ryzen 9800X3D has turned that around as a gaming powerhouse chip – the problem with that new 3D V-Cache CPU is that it’s out of stock everywhere, as noted.
