Virtualization

With AMD’s market share slowly increasing, it becomes very interesting to see where EPYC is being deployed. The latest announcement today comes from AMD and Google, with news that Google’s Compute Engine will start to offer new Confidential Virtual Machines (cVMs) built upon AMD’s Secure Encryption Virtualization (SEV) feature. These new cVMs are variants of Google’s N2D series offerings, and Google states that enabling SEV for full memory and virtualization encryption has a near zero performance penalty. Secure Encryption Virtualization in AMD’s 2nd Gen EPYC processors allows cloud providers to encrypt all the data and memory of a virtual machine at the per-VM level. These are generated on-the-fly in hardware, and are non-exportable, reducing the risk of side attacks by potentially aggressive neighbors. Previously this...
