Amazon EC2 R9g instances

R9g instances deliver up to 25% better compute performance over Graviton4-based R8g instances, with up to 35% faster performance for web applications, up to 35% for machine learning inference, and up to 30% for databases.

R9g instances are built on the AWS Nitro System. The AWS Nitro System is a combination of dedicated hardware and a lightweight hypervisor that delivers isolated multitenancy, private networking, and fast local storage.

AWS Graviton-based instances are supported by most popular Linux operating systems, including Amazon Linux. Many popular applications and services for security, monitoring and management, containers, and continuous integration and delivery (CI/CD) from AWS and software partners also support AWS Graviton-based instances. The AWS Graviton Ready program offers certified solutions from AWS Partner software vendors that you can use on AWS Graviton-based instances.

AWS Graviton5 is the latest generation of server processors designed by AWS that provide the best price performance for workloads in Amazon EC2. AWS Graviton5 processors deliver up to 25% better compute performance than Graviton4 processors.

AWS Graviton5 processors offer enhanced security with always-on memory encryption, dedicated caches for every vCPU, and support for pointer authentication. R9g instances also support encrypted Amazon Elastic Block Store (Amazon EBS).

The AWS Nitro System is a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware and software. It delivers high performance, high availability, and high security while reducing virtualization overhead. AWS Graviton5 introduces Nitro Isolation Engine, an enhancement to the AWS Nitro System, harnessing formal verification to provide mathematical certainty that customer workloads are isolated from each other and AWS operators, pioneering a new standard for mathematically proven cloud security.
