Starting today, new memory optimized Amazon Elastic Compute Cloud (Amazon EC2) R8g instances, powered by the latest-generation custom-designed AWS Graviton4 processors, are available in preview. R8g instances are built on the AWS Nitro System, a collection of hardware and software innovations designed by AWS. The AWS Nitro System enables the delivery of efficient, flexible, and secure cloud services with isolated multitenancy, private networking, and fast local storage. R8g instances offer larger instances with up to 3x more vCPUs and memory than R7g instances. Amazon EC2 R8g instances are ideal for memory-intensive workloads such as databases, in-memory caches, and real-time big data analytics.
