Up to 50% better performance than X1 instances for memory-intensive workloads

Why Amazon EC2 X2i Instances?

Amazon EC2 X2i instances are the next generation of memory-optimized instances delivering improvements in performance, price performance, and cost per GiB of memory compared to previous generation X1 instances. These instances offer a choice of 16:1 or 32:1 ratio of memory to vCPU and are ideal for memory-intensive databases and electronic design automation (EDA) workloads. X2idn and X2iedn instances are powered by 3rd generation Intel Xeon Scalable processors with an all-core turbo frequency up to 3.5 GHz and deliver up to 50% higher compute price performance than comparable X1 instances. X2idn and X2iedn instances both include up to 3.8 TB of local NVMe SSD storage and up to 100 Gbps of networking bandwidth, while X2idn offers up to 2 TiB of memory and X2iedn offers up to 4 TiB of memory. X2idn and X2iedn instances are SAP-Certified and are a great fit for workloads such as small-to large-scale traditional and in-memory databases, and analytics. 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. They feature up to 1.5 TiB of memory, and deliver up to 55% better price performance than X1e instances. X2iezn instances are a great fit for EDA workloads as well as relational databases that benefit from high single-threaded processor performance and a large memory footprint.

Benefits

Lower TCO

X2i instances deliver improvements in performance, price performance, and cost per GiB of memory compared to X1 instances. X2i instances also offer instance sizes with up to 128 vCPUs and 4,096 GiB of memory, enabling you to consolidate workloads on fewer instances and save on per-core licensing costs.

Run memory-intensive workloads

With X2idn and X2iedn instances you can run in-memory databases such as SAP HANA with up to 45% more SAPS than comparable X1 instances. Visit the SAP Partner page to learn more about SAP solutions on AWS. X2iezn instances let you run memory-intensive workloads that also require high single-threaded CPU performance, such as EDA workloads. 

Maximized resource efficiency

X2i instances are built on the AWS Nitro System, a combination of dedicated hardware and lightweight hypervisor that delivers practically all of the compute and memory resources of the host hardware to your instances for better overall performance and security.

Features

Powered by Intel Xeon Scalable processors

X2idn and X2iedn instances are powered by 3rd generation Intel Xeon Scalable processors (code named Ice Lake) and deliver up to 50% higher compute price performance than comparable X1 instances. X2iezn instances are powered by 2nd generation Intel Xeon Scalable processors (code named Cascade Lake) and deliver up to 55% better compute price performance than X1e instances.

High performance storage

X2idn and X2iedn instances support up to 80 Gbps throughput to Amazon Elastic Block Store (EBS), which is more than four times that of comparable X1 instances. X2idn and X2iedn instances also include up to 3.8 TB of local NVMe storage per instance. X2iezn instances support up to 19 Gbps throughput to Amazon EBS. 

High performance networking

X2idn, X2iedn, and X2iezn instances support up to 100 Gbps networking bandwidth, which is four times higher than comparable X1 instances. X2idn and X2iedn support the Elastic Fabric Adapter (EFA) on the largest sizes, and X2iezn support it on the largest and metal sizes.

Built on the AWS Nitro System

X2i 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 and software to deliver high performance, high availability, and high security while also reducing virtualization overhead.
