In this step, we will create databases with RDS, will a replica. We will also implement ElasticCache to provide caching for the database.
Amazon RDS is a managed database service that helps you quickly create relational databases and automates backups and failovers so you don’t have to wake up in the middle of the night to bring a database back up.
Amazon ElasticCache is an in-memory caching that provides microsecond read and write latency. ElastiCache is compatible with Redis and Memcached. We are going to be using Redis with ElasticCache.
