Starting today, memory optimized Amazon EC2 X2iezn instances are available. Amazon EC2 X2iezn instances are powered by 2nd generation Intel Xeon Scalable processors with an all core turbo frequency of up to 4.5 GHz, the fastest in the cloud. X2iezn instances deliver the highest all-core turbo CPU performance from Intel Xeon Scalable processors in the cloud, and deliver up to 55% better compute price performance than X1e instances. They are a great fit for electronic design automation (EDA) workloads as well as relational databases that benefit from high single-threaded processor performance and a large memory footprint. The combination of high single-threaded compute performance and a 32:1 ratio of memory to vCPU make X2iezn instances an ideal fit for EDA workloads including physical verification, static timing analysis, power sign-off, and full chip gate level simulation, and database workloads that are license bounded. 

Amazon EC2 X2iezn 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. 

The X2iezn instances are available in 6 sizes ranging from 8 to 48 vCPUs with 256 to 1,536 GiB of memory. X2iezn instances also feature up to 100 Gbps networking with support for the Elastic Fabric Adapter (EFA), and up to 19 Gbps of throughput to the Amazon Elastic Block Store (EBS). X2iezn instances are also available as bare metal instances, which allow EC2 customers to run applications that benefit from deep performance analysis tools, specialized workloads that require direct access to bare metal infrastructure, legacy workloads not supported in virtual environments, and licensing-restricted business critical applications. They provide your applications with direct access to the processor and memory resources of the underlying server, and you can still take advantage of all the comprehensive services and features of the AWS Cloud, such as Amazon Elastic Block Store (EBS), Elastic Load Balancer (ELB), and Amazon Virtual Private Cloud (VPC). 

The X2iezn instances are now available in the AWS US West (Oregon), US East (Northern Virginia), Europe (Ireland), and Asia Pacific (Tokyo) regions. X2iezn instances 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 X2iezn instances, visit the AWS Management Console, AWS Command Line Interface (CLI), and AWS SDKs. To learn more, visit the EC2 X2iezn instances Page, visit the AWS forum for EC2 or connect with your usual AWS Support contacts.
