General availability: Zone redundancy for Azure SQL Database general purpose tier
Published date: April 13, 2022
Your new and existing general purpose provisioned and serverless Azure SQL Database elastic pools allow for zone redundant configuration. This feature utilizes Azure Availability Zones to replicate databases across multiple physical locations within an Azure region. By selecting zone redundancy, you can make your databases and elastic pools resilient to a much larger set of failures, including catastrophic datacenter outages—without any changes of the application logic.
