What is Region Pairing?
Microsoft Azure’s region pairing is nothing but replicating the data of a region with another region that is in the same geographical area which will help to prevent loss of data in the situations like natural disasters.
If you have configured all of your data regarding your application data will be replicated automatically to other regions if you have a region pairing.
There are many advantages of region one of them is the high availability of data to your application if any one of the regions fails to deliver the data to the application then it will automatically retrieve the data from another region by that the availability of the application to the end users will be high and also the cost will also be reduced because it is having two regions to access the data from so it will reduce the load on an only single region.
