Azure Cache for Redis zone redundancy for Premium tier now generally available
Published date: 09 June, 2021
With the zone redundancy feature for Azure Cache for Redis in the Premium tier, you can deploy your caches across multiple availability zones and obtain increased availability. You can also improve redundancy by adding more replica nodes. A zone-enabled cache automatically distributes its replicating nodes over the zones that you have selected. It is more resilient to datacenter-level issues and outages.
