With AMD’s market share slowly rising, it turns into very fascinating to see the place EPYC is being deployed. The newest announcement in the present day comes from AMD and Google, with information that Google’s Compute Engine will begin to supply new Confidential Virtual Machines (cVMs) constructed upon AMD’s Secure Encryption Virtualization (SEV) characteristic. These new cVMs are variants of Google’s N2D collection choices, and Google states that enabling SEV for full reminiscence and virtualization encryption has a close to zero efficiency penalty.
Secure Encryption Virtualization in AMD’s 2nd Gen EPYC processors permits cloud suppliers to encrypt all the information and reminiscence of a digital machine on the per-VM degree. These are generated on-the-fly in {hardware}, and are non-exportable, lowering the chance of aspect assaults by probably aggressive neighbors. Previously this kind of computing mannequin was solely attainable if a bunch assumed management of an entire server, which for many use instances isn’t sensible.
With SEV2, technically AMD permits for as much as 509 keys per system. Google will supply pictures for its cVMs with Ubuntu 18.04/20.04, COS v81, and RHEL 8.2; different working system pictures might be out there sooner or later.
These cVMs might be out there in vCPU listings, confirming that simultaneous multi-threading is enabled on the {hardware}. Both Google and AMD declined to touch upon the precise EPYC CPUs getting used, solely that they had been a part of the twond Gen Rome household.
This is technically a beta launch, with Google being the primary cloud supplier to supply SEV-enabled VMs. Google can be selling the usage of its Asylo open-source framework for confidential computing, promising to make deployment straightforward at a excessive efficiency.
Quite a few 30 MB gifs had been created by Google to showcase the brand new cVMs. Rather than share them with you in an outdated 1989 format, we transformed them to video:
