### AI overview

AWS has generally released the Amazon EC2 R9g and R9gd instances, powered by AWS Graviton5 processors. These Arm-based, memory-optimized instances offer higher per-vCPU performance, faster memory, larger cache capacity, and increased networking and Amazon EBS bandwidth for database, caching, analytics, container, and microservices workloads. R9gd adds local NVMe SSD storage for low-latency local capacity. Both families use the AWS Nitro System and Nitro Isolation Engine, with AWS citing formal verification for the isolation properties.

### Source excerpt

AWS has made its Amazon EC2 R9g and R9gd instances generally available, introducing memory-optimized systems powered by AWS Graviton5 processors. The new Arm-based instances target database, caching, analytics, container, and microservices workloads that require high memory bandwidth and improved per-vCPU performance. Compared with Graviton4-based R8g instances, AWS states that R9g can deliver up to 25% The post AWS Launches Graviton5-Based EC2 R9g and R9gd Memory-Optimized Instances appeared first on StorageReview.com.

### AI overview

Amazon describes formally verifying the Nitro Isolation Engine, a separation-kernel component that enforces isolation between EC2 virtual machines. The verification uses Isabelle/HOL and is deployed as an always-on feature for Graviton5 users.

### Source excerpt

Splitting the "separation kernel" off from the rest of the Nitro security system and using only a subset of the Rust programming language to code it enabled its formal verification.
