Database Redundancy and Data Replication are the same things right?

[Ashish Pratap Singh]

Hey, yeah they are similar.

Redundancy is a bigger concept which could also mean having redundant application servers.

Hope you used redundancy for backend servers and replication for databases.

Anyways, I feel your weekly newsletter is like a refresher. Thanks. Keep going.
