$5.4950/hour on-demand · $4,011/month (Redis, Default)

cache.r6g.12xlarge is a memory-optimized ElastiCache instance with 48 vCPU and 317.77 GiB, generation 6 of the r family on AWS Graviton (Arm).

Caveat: instance price is only part of the bill. Cross-region and internet data transfer, latency to your users, data-residency rules and service availability can outweigh a few percent on compute.
