Starting today, Amazon Elastic Compute Cloud (Amazon EC2) C7g, M7g and R7g instances are now available in AWS Region US West (N. California). These instances are powered by AWS Graviton3 processors that provide up to 25% better compute performance compared to AWS Graviton2 processors, and built on top of the the AWS Nitro System, a collection of AWS designed innovations that deliver efficient, flexible, and secure cloud services with isolated multi-tenancy, private networking, and fast local storage.
