Starting today, Amazon Elastic Compute Cloud (Amazon EC2) R8i instances are available in the Israel (Tel Aviv) 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 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 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.
