The R8i and R8i-flex instances, offering improved CPU performance and memory bandwidth over previous Intel-based generations, became available in additional AWS regions. These instances deliver enhanced price-performance for memory-intensive workloads, with R8i-flex designed for common sizes suited to less compute-saturated applications.
Boasting SAP-certification and suitable for demanding applications, these instances provide notable speedups in PostgreSQL, AI recommendation, and web server workloads. While vendor data specifies percentage improvements, independent testing data was not included. Their addition diversifies AWS capacity for memory-bound cloud computing.
