The R8i and R8i-flex instances deliver up to 15% better price-performance and 2.5 times more memory bandwidth compared to previous generation Intel instances on AWS. They are reported by AWS to perform 20% better than R7i instances overall and demonstrate higher gains for workloads like PostgreSQL databases (up to 30%), NGINX web applications (up to 60%), and AI deep learning recommendations (up to 40%).
R8i-flex serves as AWS's first memory-optimized Flex instance, targeting mostly memory-intensive workloads that do not fully use compute resources. The R8i instance family includes 13 sizes up to 96xlarge, is SAP-certified delivering 142,100 aSAPS, and aims to support mission-critical SAP workloads. These announcements reflect AWS's continued expansion and specialization of EC2 offerings for demanding applications.
