每年 AWS re:Invent 要到的時候就會有很多新的消息出來，Amazon ElastiCache 的團隊應該也是配合著這一波放出消息：「Amazon ElastiCache Now Supports the R4 Node Family」。
Amazon ElastiCache now supports R4 node types. R4 nodes are optimized for latency sensitive and memory intensive workloads. They come in six sizes, providing 12.3GiB to 407GiB of available in-memory capacity. By setting up a 15-shard cluster for Redis, you can scale up to 6.1TiB of in-memory capacity. For Memcached, you can set up a 20-node cluster to support up to 8.14 TiB in-memory workloads. Equipped with the Intel Broadwell processor, and improved networking, R4 node family offers superior performance over the popular R3 node family.
這兩個應用都是看記憶體吃飯的...
