Distributed Caching

In this scenario, you have to consider the following points:

• Implement a cluster of servers that will all act as the distributed cache. Implement a data sharding process to evenly distribute the data amongst all cache servers and make sure it uses a consistent hashing algorithm to minimize cache reorganization when a server joins or leaves the cluster.
• Add cache replication to have redundancy of your data in case of a failure, that way, your distributed cache is fault-tolerant as well.
• Cache invalidation is a must on any caching solution, as your data will become stale if you don’t update it often.
