AWS offers a wide range of memory optimized instances ranging from 8 GiB on R6g instances up to 24 TiB High Memory instances. Amazon EC2 High Memory instances have the highest amount of memory of any EC2 instance with up to 24 TiB of memory. These instances are purpose-built for large in-memory databases like SAP HANA. EC2 High Memory instances are certified by SAP for running Business Suite on HANA (SoH), the next-generation Business Suite S/4HANA, Data Mart Solutions on HANA, Business Warehouse on HANA (BW), and SAP BW/4HANA in production environments. AWS Quick Start for SAP HANA helps you deploy fully functional SAP HANA systems on the AWS Cloud, following best practices from AWS and SAP.

The AWS Nitro System 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.

EC2 High Memory instances with 18 TiB and 24 TiB are the first ever EC2 instances built on 8-socket hosts powered by 2nd Generation Intel® Xeon® Scalable (Cascade Lake) processors. These instances take advantage of the innovation of the AWS Nitro System, a combination of purpose-built hardware and software components that provide the unparalleled performance, security, isolation, elasticity, and efficiency of the infrastructure that powers Amazon EC2 instances.

As customers scale up to larger in-memory database sizes, EC2 High Memory instances extend the number of choices available to customers by offering additional sizes and room for growth. Customers can start with smaller instance sizes, and easily transition to larger sizes when their data outgrows the instance. Since these are EC2 instances, customers can transition from SAP-certified X1 and X1e instances to EC2 High Memory instances as easily as they can move between 3, 6, 9, 12, 18, or 24 TiB EC2 High Memory instances.
