- Not every region is available to all. Eg: Some regions are owned by American central government so we cannot choose that region, only people working there can have access.
Region Pairs :
- Each region has one another region which is treated as pair .
- If data is present in one region then it will be also present in its pair region i.e, data backup is there in pair region.
