Increase high availability of serverless for Hyperscale with zone redundancy
Published May 09 2023 10:42 AM 2,150 Views

Serverless for Hyperscale in Azure SQL Database was recently introduced to provide compute auto-scaling benefits in the Hyperscale tier.  Serverless Hyperscale optimizes price-performance and simplifies performance management for databases with intermittent and unpredictable usage while leaving room for growing to extreme scale and delivering high performance during active usage periods.


We are pleased to announce that the serverless Hyperscale preview now also supports zone redundancy to enable even greater high availability.  Zone redundancy helps ensure business continuity in the event of a data center outage.  It is simple to enable in the Azure portal or API experiences, and does not require any application changes.  The only requirements are that the primary replica has at least one high availability replica and that the backup storage type is zone redundant or geo-zone redundant.  The service automatically handles ensuring replicas are distributed across zones in the region.  There is no additional cost for enabling zone redundancy in Hyperscale beyond the cost of the primary and HA replicas.
