Now in preview, your new and existing Azure SQL Databases and elastic pools that use the general purpose tier can enable the zone redundant configuration. The zone redundant configuration utilizes Azure Availability Zones to replicate databases across multiple physical locations within an Azure region. By selecting zone redundancy, you can make your general purpose single databases and elastic pools resilient to a much larger set of failures, including catastrophic datacenter outages, without any changes of the application logic.

How to enable the zone redundant configuration


 


The zone redundant configuration can be enabled for both new and existing general purpose databases and elastic pools. Once the zone redundant option is enabled, Azure SQL Database will automatically reconfigure the database or pool. You can configure this setting by using Portal, CLIPowerShell, or ARM API.


 


Portal


 


The following diagram illustrates how to use Azure portal to configure a general purpose elastic pool to be zone redundant.
