Are Availability Zones physically separated? If yes, what is the distance between AZs? RRS feed

  • Question

  • Hello,

    I would like more information on Availability Zones and physical separation. Are they physically separated and if yes, how are between AZs?

    I'm building an application that requires physical separation and would like know if AZs are the answer.

    Thanks

  • Hi SFVG,

    Azure Availability Zones are physically independent locations consisting of one or more data centers with redundant power, network, and cooling. Distribution of the zones are based on a per-region risk assessment and the distances vary across regions. All Availability Zones in a region are located within the network latency boundary of an Azure region to allow customers to run highly-available mission-critical applications with synchronous replication.

  • Does this mean you can build SQL Server S2D based clusters with nodes based in different Availability Zones? If so, can you provide a link that states this is a valid configuration? Thanks!
