Starting today, memory optimized Amazon EC2 X2idn and X2iedn instances are generally available. X2idn and X2iedn instances 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. These new instances are powered by 3rd generation Intel Xeon Scalable Processors (Ice Lake) and deliver up to 50% higher compute price performance than comparable 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.  

X2idn instances are available in three sizes ranging from 64 to 128 vCPUs with 1,024 to 2,048 GiB of memory. X2iedn are available in seven sizes ranging from 4 to 128 vCPUs with 128 to 4,096 GiB of memory. X2idn and X2iedn instances offer a new 24xlarge size with 1.5TiB and 3TiB of memory respectively, enabling customers to right-size workloads and lower cost. 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. 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, and are designed to meet the reliability needs of mission-critical workloads. Customers can use the new EBS IO2 Block Express volumes, which deliver sub-millisecond latency and 99.999% durability, with the new X2idn and X2iedn instances. 

Amazon EC2 X2idn and X2iedn instances are built on the AWS Nitro System, which is a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware, delivering high performance, high availability, and highly-secure cloud instances. X2idn and X2iedn deliver up to 45% more SAPS than comparable X1 instances and are SAP-Certified for running Business Suite on HANA, SAP S/4HANA, Data Mart Solutions on HANA, Business Warehouse on HANA, SAP BW/4HANA, and SAP NetWeaver workloads on anyDB. You can view the certification data on the Certified and Supported SAP HANA Hardware Directory.  

X2idn instances are available in the following AWS Regions: US East (N. Virginia), Asia Pacific (Mumbai, Singapore, Tokyo), and Europe (Ireland, Frankfurt). X2iedn instances are available in the following AWS Regions: US East (Ohio, N. Virginia), US West (Oregon), Asia Pacific (Singapore, Tokyo), and Europe (Ireland, Frankfurt).  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. To get started with X2idn or X2iedn instances, visit the AWS Management Console, AWS Command Line Interface (CLI), and AWS SDKs.
