Amazon Elastic Compute Cloud (Amazon EC2) has released the U7i instances, which were first previewed in re: Invent 2023. These instances boast up to 32 TiB of DDR5 memory and 896 vCPUs, running on custom 4th generation Intel Xeon Scalable processors (Sapphire Rapids). These high-memory instances are ideal for in-memory databases like SAP HANA, Oracle, and SQL Server. Different configurations are available, offering various memory sizes and bandwidth options to suit different workload demands.
The U7i instances deliver superior compute price performance for large in-memory workloads compared to previous EC2 High Memory instances. With over 135% more compute performance, up to 115% more memory performance, and 2.5x EBS bandwidth, data loads and cache updates are significantly faster. The instances also support ENA express with 25 Gbps of bandwidth per flow and provide an 85% improvement in latency between instances.
Additionally, each U7i instance can connect to 128 EBS volumes and is certified by SAP to run various SAP applications in production environments. Operating systems supported include Amazon Linux, Red Hat Enterprise Linux, SUSE Linux Enterprise Server, Ubuntu, and Windows Server. AWS is also working on releasing even larger instances later this year to meet evolving customer needs.
These new instances are available in the US East (N. Virginia), US West (Oregon), and Asia Pacific (Seoul, Sydney) AWS regions. They can be purchased in On-Demand, Savings Plan, and Reserved Instance formats, with shared options, Dedicated instance, and Dedicated host tenure. For those interested in migrating to AWS with SAP applications, AWS Launch Wizard for SAP is a helpful resource to consider.
In summary, the U7i instances from Amazon EC2 provide high-performance computing capabilities for demanding in-memory database workloads like SAP HANA. With impressive memory and compute power, along with efficient data transfer speeds and bandwidth options, these instances are a valuable addition to the AWS ecosystem for organizations looking to optimize their cloud infrastructure for large-scale data operations.
