You can now take advantage of the M3 and R3 cache nodes with Amazon ElastiCache.
R3 cache nodes are memory-optimized and support enhanced networking, ideal for your in-memory and caching workloads. These new cache nodes can deliver higher sustained memory bandwidth with lower network latency and jitter. M3 cache nodes provide better, more consistent performance than M1 cache nodes. The new M3 and R3 cache nodes also represent cost savings of 16%-25% compared to M1 and M2 families.
The M3 cache nodes are available in all AWS regions where ElastiCache is available. R3 cache nodes are available in all AWS regions except South America (São Paulo).
