https://www.techpowerup.com/272808/amd-epyc-processors-optimized-for-vmware-vsphere-7-0u1 AMD today highlighted the latest expansion of the AMD EPYC processor ecosystem for virtualized and hyperconverged infrastructure (HCI) environments with VMware adding support for AMD Secure Encrypted Virtualization-Encrypted State (SEV-ES) in its newest vSphere release, 7.0U1. With the latest release, VMware vSphere now enables AMD SEV-ES, which is part of AMD Infinity Guard, a robust set of modern, hardware enabled features found in all 2nd Gen AMD EPYC processors. In addition to VM memory encryption, SEV-ES also provides encryption of CPU registers and provides VMware customers with easy-to-implement and enhanced security for their environments.
"As the modern data center continues to evolve into a virtualized, hybrid cloud environment, AMD and VMware are working together to make sure customers have access to systems that provide high levels of performance on virtualization workloads, while enabling advanced security features that are simple to implement for better protection of data," said Dan McNamara, senior vice president and general manager, Server Business Unit, AMD. "A virtualized data center with AMD EPYC processors and VMware enables customers to modernize the data center and have access to high-performance and leading-edge security features, across a wide variety of OEM platforms."
In my personal opinion high VM performance is meaningless unless you have good security to go with it.
