Amazon ElastiCache Serverless adds more control over scaling the cache, by enabling customers to set a minimum limit for data storage and request rate. With ElastiCache Serverless, you can create a highly available and scalable cache in less than a minute by just specifying a name. ElastiCache Serverless automatically scales to accommodate your workload’s fluctuating traffic patterns. Now, you can pre-scale a serverless cache for anticipated scaling events by setting a minimum usage limit for data storage or request rate.
