Replication happens across multiple servers where data is replicated continuously. With replication, we get redundancy, and simultaneously data availability takes a spike. This also leads to generating multiple copies of data on multiple servers. With replication, databases are secure. Data recovery from hardware failure and service interruptions is also possible through replication. Also, if your data is very significant to you, it is all safe and sound with replication. Furthermore, data is available for your applications round the clock.
