Protecting data in use
AWS confidential computing is always on. There is no mechanism for any AWS operator to access customers' Amazon Elastic Compute Cloud (Amazon EC2) instances within the AWS Nitro System.
Benefits
Confidential computing capabilities
Supporting the most demanding use cases
Nitro System
Provides confidentiality and isolation from AWS operators.
Nitro Enclaves
Allows customers to create isolated compute environments to protect highly sensitive data from their own users and applications.
NitroTPM
Allows customers to attest to the integrity of their instances by providing cryptographic proof.
Memory encryption
Starting with AWS Graviton2, AMD EPYC (Milan), and Intel Xeon Scalable (Ice Lake) processors, instance memory is always encrypted. Instances that are enabled with AMD SEV-SNP use an instance-specific key for their memory encryption.
