Intel Ice Lake supports only remote attestation based on Intel Software Guard Extensions Data Center Attestation Primitives (Intel SGX DCAP) and does not support remote attestation based on Intel Enhanced Privacy ID (EPID). You must adapt applications before you can use the remote attestation feature. For more information about remote attestation, see Strengthen Enclave Trust with Attestation.
Intel SGX depends on host hardware. This instance family does not support hot migration.
Operations, such as changing instance types and enabling the economical mode, may cause the host of an instance to change. For instances of this instance family, the host change may cause data decryption to fail. Proceed with caution.
By default, failover is disabled. You can enable failover. For more information, see Modify instance maintenance attributes. Failover causes the host of an instance to change. For instances of this instance family, the host change may cause data decryption to fail. Proceed with caution.
When you create a security-enhanced instance, you must select a dedicated image to use the security features. For more information, see Create a trusted instance.
