Starting today, memory optimized Amazon EC2 X2idn and X2iedn instances are available in US West (Northern California). X2idn and X2iedn instances, powered by 3rd generation Intel Xeon Scalable Processors and built using AWS Nitro System, are designed for memory-intensive workloads and deliver improvements in performance, price performance, and cost per GiB of memory compared to previous generation X1 instances. X2idn has a 16:1 ratio of memory to vCPU and X2iedn has a 32:1 ratio, making these instances a great fit for workloads such as in-memory databases and analytics, big data processing engines, and Electronic Design Automation (EDA) workloads.

EC2 X2idn and X2iedn instances offer the highest Amazon Elastic Block Store (EBS) performance of Amazon EC2 instances with up to 80 Gbps bandwidth and 260k IOPS. X2idn and X2iedn instances offer 100Gbps networking throughput with EFA support, and are ideal for workloads like EDA and HPC that need high network performance.

With this launch, X2idn and X2iedn instances are available in the following AWS Regions: US East (Ohio, N. Virginia), US West (Oregon, Northern California), Asia Pacific (Jakarta, Mumbai, Seoul, Singapore, Sydney, Tokyo), Canada (Central), Europe (Frankfurt, Ireland, London, Milan, Paris, Stockholm), South America (São Paulo) and AWS GovCloud (US). X2idn instances are available in four sizes ranging from 64 to 128 vCPUs with 1,024 to 2,048 GiB of memory. X2iedn are available in eight sizes ranging from 4 to 128 vCPUs with 128 to 4,096 GiB of memory. X2idn and X2iedn will be available for purchase with Savings Plans, Reserved Instances, Convertible Reserved, On-Demand, and Spot instances, or as Dedicated instances or Dedicated hosts.
