Fail safe/redundancy in case of a data store failure.

[Ram Kishore]

Hi, I am working on a healthcare project which is practically built on GCP. 

The requirement is, we need to write data in multiple zone of a region or if possible multiple zones of different region. 

This is needed so that when one zone or an entire region is down, we still have our application working by fetching data from other zones. 

Practically I need a fail safe/redundancy in case of a data store failure.
