Azure SQL Database Premium tier supports multiple redundant replicas for each database that are automatically provisioned in the same datacenter within a region. This design leverages the SQL Server AlwaysON technology and provides resilience to server failures with 99.99% availability SLA and RPO=0. With the introduction of Azure Availability Zones, we are happy to announce that the SQL Database now offers built-in support of the Availability Zones in its Premium service tier.
