Compared to normal Redis-Paas, it's on the same line, probably cheaper than the average price on ther market. ElastiCache is basically a way to spin up a EC2-backed instance of Redis, with automatic failover and replication. It only handles one node per cluster, and doesn't handle scaling (you need to manual provision, replicate, switch, etc.). But if you go with a true clustering solution (like Redis Cloud, www.redis-cloud.com), then you get automatic transparent scaling with zero downtime thanks to dynamic sharding: http://redis-cloud.com/redis/redis-comparison http://redis-cloud.com/redis/redis-comparison To me, such a cluster solution justifies the PaaS price over a manual Redis installation.
