In our services, some of the information inside the database is not required to retrieve frequently from there. In such cases, we use ElastiCache in order to reduce the load from the database especially RDS.

configuration data
user login detail data
application permission data

not to get lost cache data in order to change ElasitCache instance type
most of the time cache data are not distributively stored to secondary, mostly goes to primary
default TTL should be 30 days or 60 days instead of infinity

obviously fast to retrieve data
able to reduce waiting time instead of RDS
able to reduce cost by the way of using some data in RDS

memcached should be improved like Redis
need serverless with Aurora RDS
cost should be decreased

We use ElastiCache as a general purpose cache layer in its Memcached compatible mode. This is in our backend stack and used to store anything which needs to be shared between multiple hosts. Primarily, this is database query result sets but does include a number of other items too.

Easy to set up and zero maintenance
Relatively low cost
Drop-in replacement for Memcached service

Doesn't quite have all the same rich feature set in some places. Some of the more advanced setups may not be able to be replicated on ElastiCache, so if you need to do anything in that area you may need to rethink the architecture or run your own nodes instead.

Basically, zero-maintenance Memcached clusters, meaning the time can be spent elsewhere rather than looking after our own.
