After having installed the Redis server, and used the Redis command line, we discussed more advanced concepts like sharding. We will now continue in a similar path with the next lesson of the “Redis a NoSQL key-value store” course.
In this lesson, we will focus on Replication. Replication is a very important feature of any data-oriented solution: either sophisticated relation database or simple key/value store. Replication allows having many copies of your data to be distributed across many nodes (servers), data centers and/or geographical regions.
Replication in Redis can be a bit tricky to configure, but can lead to a very robust architecture.
