General availability: Zone-redundant Azure SQL databases and elastic pools
Posted on Wednesday, June 27, 2018
Zone-redundant SQL single databases and elastic pools are now generally available in select regions.
The zone-redundant configuration is available to SQL single databases and elastic pools in the Premium service tier at no extra cost. Enabling this option results in moving individual database replicas to different availability zones in the same region. It makes databases and elastic pools resilient to a much larger set of failures, including catastrophic datacenter outages. The supported regions now include France Central and Central US.
