Elasticache overview

Role: SREs, CloudOps, and DevOps who are admins.

AWS ElastiCache is a web service that makes it easy to deploy, operate, and scale an in-memory data store and cache in the AWS cloud. The service improves the performance of web applications by allowing you to retrieve information from fast, managed, in-memory data stores, instead of relying entirely on slower disk-based databases.

ElastiCache supports two popular in-memory caching engines:

• Redis: A fast, open-source, in-memory key-value store that supports advanced data structures, persistence, and replication.
• Memcached: A simple, high-performance, distributed memory object caching system.

This is also managed by AWS. Hence, in case of any failed nodes, AWS will take care by creating new ones without impacting the application.

AWS ElastiCache helps in playing a significant role in cloud monitoring by improving the performance of monitoring systems, reducing latency, and enabling real-time data processing.
