Case Study: Etermax achieves continuous availability, scales to 25M daily users and cuts AWS costs with Redis Enterprise (Redis)

Etermax Scales its Popular Gaming Platform with the Continuous Availability of Redis Enterprise

Etermax, the studio behind hit games like Trivia Crack and Pictionary, outgrew its open-source Redis setup as user numbers exploded—adding millions weekly. Single-threaded Redis created CPU bottlenecks, pre-sharded memory limits capped scaling, and the cost of maintaining fully redundant infrastructure made high availability impractical.

Deploying Redis Enterprise in its VPC solved those limits: auto-sharding, auto-scaling and multiple instances per server let Etermax scale to 25 million daily users with no downtime, while in-memory replication and auto-failover improved reliability. The change increased server throughput (up to 95% CPU utilization), cut AWS infrastructure costs by about 30%, and opens the door to up to 70% additional savings by moving cold data to flash.
