Amazon ElastiCache Serverless is a new serverless option for creating highly available, scalable in-memory caches. It simplifies cache setup and management by automatically handling provisioning, scaling, and maintenance. Users only need to provide a cache name, and ElastiCache Serverless creates an endpoint accessible within their VPC in under a minute. The service continuously monitors resources and scales instantly to meet application demands without downtime or performance issues. ElastiCache Serverless offers pay-per-use pricing, charging only for stored data and compute used by cache requests. This solution optimizes resources and lowers total cost of ownership for modern applications requiring real-time performance.
