Starting today, Amazon Elastic Compute Cloud (Amazon EC2) R8i and R8i-flex instances are available in the Europe (Milan) region. These instances are powered by custom Intel Xeon 6 processors, available only on AWS, delivering the highest performance and fastest memory bandwidth among comparable Intel processors in the cloud. The R8i and R8i-flex instances offer up to 15% better price-performance, and 2.5x more memory bandwidth compared to previous generation Intel-based instances. They deliver 20% higher performance than R7i instances, with even higher gains for specific workloads. They are up to 30% faster for PostgreSQL databases, up to 60% faster for NGINX web applications, and up to 40% faster for AI deep learning recommendation models compared to R7i.

R8i-flex, our first memory-optimized Flex instances, are the easiest way to get price performance benefits for a majority of memory-intensive workloads. They offer the most common sizes, from large to 16xlarge, and are a great first choice for applications that don't fully utilize all compute resources.

R8i instances are a great choice for all memory-intensive workloads, especially for workloads that need the largest instance sizes or continuous high CPU usage. R8i instances offer 13 sizes including 2 bare metal sizes and the new 96xlarge size for the largest applications. [R8i instances are SAP-certified](https://docs.aws.amazon.com/sap/latest/general/sap-hana-aws-ec2.html) and deliver 142,100 aSAPS, the highest among all comparable machines in on-premises and cloud environments, delivering exceptional performance for mission-critical SAP workloads.

To get started, sign in to the [AWS Management Console](https://aws.amazon.com/console/). Customers can purchase these instances via Savings Plans, On-Demand instances, and Spot instances. For more information about the new [R8i and R8i-flex](https://aws.amazon.com/ec2/instance-types/r8i) instances visit the AWS News [blog](https://aws.amazon.com/blogs/aws/best-performance-and-fastest-memory-with-the-new-amazon-ec2-r8i-and-r8i-flex-instances/).
