In 2026, AWS broadened the deployment of Amazon EC2 R8id instances to Asia Pacific, Canada, and Europe. These instances feature up to 22.8 TB of NVMe SSD local storage—triple the capacity of previous R6id models—and offer up to 3.3 times greater memory bandwidth. AWS claims a performance improvement of up to 43% compared to R6id, which is suited for memory-intensive applications like in-memory databases and real-time analytics.
Additionally, AWS introduced flexibility in bandwidth allocation by allowing a 25% adjustment of network and Amazon EBS throughput using EC2 instance bandwidth weighting. Select instance sizes also support Elastic Fabric Adapter networking. The instances are accessible via Savings Plans, On-Demand, and Spot purchasing options.
