Azure Storage now offers Zone Redundant Storage for general availability.
Microsoft offers Locally Redundant Storage (LRS), Geographically Redundant Storage (GRS), and Read Access-GRS (or RA-GRS). LRS has multiple replicas in a region, and GRS has multiple copies replicated across two regions that are at least 400 miles apart. Zone Redundant Storage (ZRS) provides a redundancy option that is in between and has multiple copies replicated.
