AWS announces the general availability of Amazon Elastic Compute Cloud (Amazon EC2) C7gd, M7gd, and R7gd metal instances with up to 3.8 TB of local NVMe-based SSD block-level storage. They have up to 45% improved real-time NVMe storage performance than comparable Graviton2-based instances. These instances are built on the AWS Nitro System and are great fit for applications that need access to high-speed, low latency local storage, including those that need temporary storage of data for scratch space, temporary files, and caches. C7gd instances are ideal for high performance computing (HPC), and ad serving. M7gd instances are ideal for general purpose workloads such as application servers, and microservices. R7gd instances are ideal for memory-intensive workloads such as open-source databases, and real-time big data analytics.
