  Google’s new Confidential Virtual Machines on 2nd Gen AMD EPYC

  "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 sort of computing model was only possible if a host assumed control of a whole server, which for most use cases isn’t practical.
  ...
  With SEV2, technically AMD allows for up to 509 keys per system. Google will offer images for its cVMs with Ubuntu 18.04/20.04, COS v81, and RHEL 8.2; other operating system images will be available in due course."
