RA-GRS provides geo-replication across two regions, with read-only access to the data in the secondary location. This will maximize the availability of your storage account. When you enable RA-GRS, your data will be available on a primary and a secondary endpoint for your storage account as well. The secondary endpoint will be similar to the primary endpoint, but it appends the secondary suffix to it. The access keys that are generated for your storage account can be used for both endpoints.

Now that we have covered the different storage replication types that are set when you create a storage account, we can look at the different storage accounts that Azure has to offer.
