Reliability in Azure Chaos Studio

This article describes reliability and availability zones support in Azure Chaos Studio. For a more detailed overview of reliability in Azure, see Azure reliability.

Availability zone support

Availability zones are physically separate groups of datacenters within each Azure region. When one zone fails, services can fail over to one of the remaining zones.

For more information on availability zones in Azure, see What are availability zones?.

Azure Chaos Studio supports zone redundancy as the default configuration within a region. Chaos Studio resources are automatically duplicated or distributed across different zones.

Prerequisites

The following regions support availability zones for Chaos Studio:

For detailed information on the regional availability model for Azure Chaos Studio see Regional availability of Azure Chaos Studio.

Zone down experience

In the event of a zone-wide outage, you should anticipate a brief degradation in performance and availability as the service transitions to a functioning zone. This interruption does not depend on the restoration of the affected zone, as Microsoft-managed services mitigate zone losses by using capacity from alternative zones. In the event of an availability zone outage, it's possible that a chaos experiment could encounter errors or disruptions, but crucial experiment metadata, historical data, and specific details should remain accessible, and the service should not experience a complete outage.

Cross-region disaster recovery and business continuity

Chaos Studio supports single-region geography only, and doesn't support service enabled cross-region failover.
