Intel TDX and AMD SEV-SNP are CPU primitives for hardware-assisted confidential virtualization.
They enforce hardware-level separation between system software and the confidential VM, encrypt memory at run-time, and change the hypervisor from overseer to facilitator.
Confidential virtualization is not the same as confidential cloud, and it is a foundational shift in virtualization security.
While TDX and SEV-SNP are enabling primitives, they do not provide a confidential computing cloud alone, requiring a system-wide trust architecture and ecosystem.
