HPC Cloud Updates WE 09 Nov 2025

Updates to AWS, Azure & GCP in the last week relevant for HPC practitioners. Memory optimized VMs from both Azure and AWS in the form of the HPC specific HBv5 on Azure and the R8a on AWS. Google gives us new TPUs and Axion powered VMs too.

AWS

Everything HPC that happened in AWS last month

October was busy for HPC in the cloud | Amazon Web Services
It’s been a busy month in the world of HPC on AWS: we’ve seen new data sets, refinements to cluster operations, and deeper thinking about how workloads map to infrastructure. For our customers driving R&D with HPC, those changes matter (and yes, the nerd in me is quietly excited). In today’s post, we’ll tell you […]

New TPUs and Axion powered VMs with the N4A

Ironwood TPUs and new Axion-based VMs for your AI workloads | Google Cloud Blog
Google Cloud’s compute portfolio now includes Ironwood TPUs and Axion-based N4A VMs and C4A bare metal.

Need bare metal in your ARM flavoured cloud compute. You can get Axion in bare metal flavours now

New Axion C4A metal offers bare metal performance on Arm | Google Cloud Blog
C4A.metal is Google Cloud’s first Axion bare metal machine type, providing custom Arm CPUs for workloads like Android dev and automotive simulation.

They also claim Axion is twice as good on a price performance basis than x86 based VMs. Show your work please. I don’t believe you and our testing shows otherwise. Ah yes sorry there’s that sneaky “up to” in the headline…. That statement isn’t true for anything shaped like HPC I’m afraid...

Axion-based N4A VMs now in preview | Google Cloud Blog
Lower the TCO of scale-out workloads like GKE and web servers. Google Cloud’s new N4A VMs deliver breakthrough price-performance and flexible shapes.
