Azure Availability Zones (AZ) provide protection from datacenter failures by using in-region redundancy between datacenters in separate zones, each with its own independent infrastructure. If a zone is impacted by an outage, another zone will be used instead, automatically. Availability Zone support in North Europe makes the service processes in this region more resilient to datacenter outages, without requiring user intervention or extra charges. To ensure you also keep your data safe and available in the face of a datacenter outage, link your workspace to a dedicated cluster that uses Availability Zones (now enabled by default in regions that support AZ).
For more information see Availability zones in Azure Monitor.
