# SEV vs SGX Links: [[AMD SEV|SEV]], [[SGX]] ## Insights taken from [[OC3 2022 Notes]] - [[AMD SEV|SEV]] has a much larger TCB than [[SGX]], even if SGX is used with [[Gramine]]. - SEV is well suited for backwards compatibility of existing applications, while new use cases which have the opportunity to rewrite the app from scratch should consider using a more TEE-native solution such as SGX ## SEV ### SEV is best for cloud computing SEV is especially relevant to cloud computing environments, where VMs are hosted on remote servers which are not under the control of the VMs' owners, since it can reduce the amount of trust VMs need to place in the hypervisor and administrator of their host system. - [Source](https://documentation.suse.com/sles/15-SP1/single-html/SLES-amd-sev/index.html#sec-amd-sev-intro) ### SEV does not require rewriting or recompiling applications to use ![[Google Cloud Confidential Computing#^2f64b3]]
