SEV: No changes are required to the apps, better performance, but bigger TCB. GCP mitigate this with Shielded VMs, in particular integrity of the kernel in your trusted boundary, notifications to users if the integrity state changed from the baseline and made it default and free. https://cloud.google.com/blog/products/identity-security/sec... SGX: smaller TCB, but limited scale, and you have to partition your app to secure and no-secure parts using one of the SDK available, Intel SGX SDK, Microsoft OpenEnclave or Google Asylo.
