SVVP is th server virtualization validation program. It is a policy that allows administrators running running Windows Server on virtualization technologies other than Hyper-V and Microsoft Virtual Server to receive technical support for Windows Server from Microsoft. For example, VMware is one of those so certified.
This is not an issue according to AWS:
AWS does not need to be SVVP validated for customers to be fully supported running Microsoft workloads on AWS. As Microsoft explains: “SVVP does not apply to vendors that are hosting Windows Server or other Microsoft products through the Microsoft Service Provider License Agreement Program.
