The availability of data is a very big concern. Bigtable replication copies our data across multiple regions or zones within the same region, thus increasing the availability and durability of our data. Of course, to use replication, we must create an instance with more than one cluster or add clusters to an existing instance. Once this is set up, Bigtable will begin to replicate straight away and will store separate copies of our data in each zone where our instance has a cluster. Since this replication is done in almost real time, it makes for a good backup of our data. Bigtable will perform an automated failover when a cluster become unresponsive.
