Arm yourself with the cloud, a trend now with the adoption of Google Cloud • The Register
Comment It’s been a tough year for Arm. First, the British chip designer lost a financial boost with its sale to Nvidia killed by regulatory scrutiny. Then Arm laid off staff as it planned an initial public offering, and now market conditions aren’t good for that IPO.
The good news for Arm is that the cloud world has increasingly warmed to the alternative instruction set architecture. Latest sign to date: Wednesday’s presentation by Google Cloud of its first An Arm-based cloud instance, which the cloud service provider says “will deliver exceptional single-threaded performance at an attractive price.”
Designed for “scalable, cloud-native workloads”, Google Cloud’s Tau T2A virtual machines are powered by Ampere Computing Arm-based Altra processors. This means that Arm-enabled VMs, available now in preview in the US and Europe, are expected to provide excellent performance-to-cost ratio for things like web servers, containerized microservices, media transcoding, and large-scale Java applications.
Google Cloud seems pretty excited about what Arm can bring to the cloud world, given that it plans to let customers and partners try out T2A VMs for free for a trial period to “help kickstart development.” “. Even when T2A becomes generally available later this year, Google Cloud said it “will continue to offer a generous trial program that offers up to 8 vCPUs and 32 GB of RAM at no cost.”
The T2A instance is part of Google Cloud’s Tau VM family that debuted last year with instances running on AMD’s third-generation Epyc Milan processors. The Arm-based instance type supports up to 48 vCPUs per VM and 4 GB of memory per vCPU, and network bandwidth can be up to 32 Gbps. It also comes with a “wide range of network storage options”.
There is however some limitations for T2Athat also exist for the AMD-based T2D instance: no support for extended memory, single tenancy, nested virtualization, or custom VM shapes.
While Google Cloud didn’t provide any performance comparisons with x86-based instances, Ampere took the plunge and said a T2A instance with 32 of its vCPUs was up to 31% faster than the N2 instance. from Google using Intel’s Ice Lake silicon with the same number of vCPUs. . This was based on an estimated score for the standard SPEC CPU 2017 Integer Rate benchmark.
Using the cloud provider’s VM pricing guide, Ampere said a T2A instance offers up to 65% better value for money than the Intel-based N2 instance for on-demand pricing .
What about software support?
As the cloud world has been largely rooted in x86 chips most of the time, it’s fair to wonder how Ampere’s Arm-based Altra processors can handle a wide range of software.
To that end, Ampere does its best to give people confidence that its processors are up to a variety of cloud tasks. In a Wednesday blog postthe company noted how “the Arm-based server ecosystem has matured rapidly over the past few years with widely tested open source cloud-native software stacks deployed on Ampere Altra-based servers”.

“For example, Ampere runs over 135 popular applications on 5 different cloud-native infrastructures to ensure our customers have confidence in the Ampere software environment across the market,” wrote Jeff Wittich, Chief Product Officer of Ampere. .
The startup’s server chips also support multiple flavors of Linux, including Ubuntu, Red Hat Enterprise Linux, and CentOS Stream.
Wittich pointed out that Ampère has a section on its website with a large list of applications, programming languages and other types of software that have been tested on its Arm processor cores.
Google Cloud managed to get testimonials from a few independent software developers who said porting their code to T2A was easy.
“We were pleasantly surprised by the ease of portability to the Arm instance from day one. The maturity of the T2A platform gives us the confidence to start using these VMs in production,” said Khawaja Shams, CEO of Momento, a startup providing serverless caching services. .
T2A has also gained academic endorsement, with Christoph Gorgulla, a research associate at Harvard University, saying the instance’s “improved price-performance ratio” has helped his team “screen more compounds and therefore to discover more promising drug candidates”.
Several major cloud providers are now on the Arm bandwagon
With the latest introduction of Arm-based cloud instances, the British chip designer’s ISA is now supported by six of the world’s largest cloud service providers: Amazon Web Services, Microsoft Azure, Google Cloud, Alibaba Cloud, Tencent Cloud and Oracle Cloud. Other cloud providers also support Arm, such as JD Cloud, UCloud, and Equinix Metal.
All of this means that it’s very safe to say that cloud providers adopting Arm are definitely a current trend.
This is a development that would have been unthinkable for some people a decade ago, like GitHub engineer Jaana Dogan put it on twitter.
If you asked me 10 years ago that ARM may potentially be the new go-to choice for servers, I'd assume you are from a parallel universe. It happened, quickly and smoothly. Graviton's success paid a huge role making this happen. https://t.co/WTmFEDBsu7

Integrating Arm chips into server-level environments, running operating systems such as Linux, required a great deal of cooperation between the software and hardware worlds, primarily to agree and stick to a base standard of features and expectations in these computers. This made building and running software on Arm systems, especially server cases, relatively boring: it should work like x86, and it seems to.
AWS also helped pave the way for the rise of Arm in the cloud with its decision to design an Arm-based server processor in-house using the talent it picked up during Amazon’s acquisition in 2015 from chip designer Annapurna Labs. The cloud giant is now on the third generation of its Graviton chip, now available in Elastic Compute Cloud instances and for which it continues to make great price-performance claims against x86 chips.
That said, when you consider all the other major cloud providers introducing Arm-based instances, as well as some of the smaller ones, there is one common element that ties them all together: Ampere Computing.
Founded by former Intel executive Renee James, the Silicon Valley-based startup recently said growing support for its Altra processors from a variety of companies and cloud providers shows the chips are better suited. to cloud applications than those from Intel or AMD.
Like Arm, Ampere is also plan an IPO at some point, assuming market conditions eventually improve. If you’re curious about how Ampere’s chip designs are well suited for cloud applications, we suggest reading our recent interview with Ampere Director Jeff Wittich.
While the growing adoption of Arm by the cloud world is a welcome sign for anyone tired of Intel’s dominance in the space, the question now is how long will Arm’s partners and silicon like Ampere and AWS can keep that momentum going. After all, Intel and AMD both plan to introduce specialized cloud chips in the near future, and who knows, maybe RISC-V can shake things up Even further. ®
