Now available: 48xlarge and metal-48xl sizes for EBS optimized Amazon EC2 instances

Today, AWS announces the general availability of the Amazon Elastic Block Storage (Amazon EBS) optimized Amazon Elastic Compute Cloud (Amazon EC2) C8gb, M8gb, and R8gb instances in 48xlarge sizes. We are also offering C8gb and R8gb in metal-48xl sizes. These instances are powered by AWS Graviton4 processors to deliver up to 30% better compute performance than AWS Graviton3 processors. At up to 300 Gbps of EBS bandwidth, these instances offer the highest EBS performance among non-accelerated compute EC2 instances. Take advantage of the higher block storage performance offered by these new EBS optimized EC2 instances to scale the performance and throughput of a wide variety of workloads.

For increased scalability, these instances offer sizes up to 48xlarge, including two metal sizes (C8gb and R8gb only), 3 varieties of memory to vCPUs ratios, up to 300 Gbps of EBS bandwidth, up to 400 Gbps of networking bandwidth. Offering up to 1440K IOPS, these instances have the highest Amazon EBS IOPS performance in Amazon EC2. These new instances support Elastic Fabric Adapter (EFA) networking, which enables lower latency and improved cluster performance for workloads deployed on tightly coupled clusters.

The new instance sizes are available in US East (N. Virginia) and US West (Oregon) regions. Metal sizes are only available in US East (N. Virginia) region.
