Amazon EC2 [supports AMD SEV-SNP](https://aws.amazon.com/de/about-aws/whats-new/2023/04/amazon-ec2-amd-sev-snp/).
Regarding (3), AWS provides direct access to attestation statements.
However, regarding (5), attestation is partially based on the [NitroTPM](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/nitrotpm.html) for [measured boot](../architecture/attestation.md#measured-boot), which is a vTPM managed by the Nitro hypervisor.
Hence, the hypervisor is currently part of Constellation's TCB.
Regarding (4), the [firmware is open source](https://github.com/aws/uefi) and can be reproducibly built.
## Microsoft Azure

[TDX on Google](https://cloud.google.com/blog/products/identity-security/confidential-vms-on-intel-cpus-your-datas-new-intelligent-defense) is in public preview.
With it, Constellation would have a similar TCB and attestation flow as with the current SEV-SNP offering.
