General availability: Zone-redundant storage

30 March 2018

Azure zone-redundant storage, which was previously in public preview, is now generally available.  

Zone-redundant storage greatly simplifies development of highly available apps by replicating your data to different Availability Zones, with inserts and updates to data being performed synchronously across these Availability Zones. You can continue with read and write operations on your data even when one of the Availability Zones is unavailable or unrecoverable.

Availability Zones provide fault isolation through physical separation. Each zone consists of one or more data centres with independent power, network and cooling. Consider zone-redundant storage for apps where highly available read and write access is required in an Azure region.

From 1 Jun 2018, generally available pricing will be in place. Preview pricing will continue until that date. For more details on zone-redundant storage – including regional availability, pricing and migration – see the documentation.
