Reliability in Azure API Center
This article describes reliability support in Azure API Center. For a more detailed overview of reliability in Azure, see Azure reliability.
Availability zone support
Azure availability zones are at least three physically separate groups of datacenters within each Azure region. Datacenters within each zone are equipped with independent power, cooling, and networking infrastructure. In the case of a local zone failure, availability zones are designed so that if the one zone is affected, regional services, capacity, and high availability are supported by the remaining two zones.
Failures can range from software and hardware failures to events such as earthquakes, floods, and fires. Tolerance to failures is achieved with redundancy and logical isolation of Azure services. For more detailed information on availability zones in Azure, see Regions and availability zones.
Azure availability zones-enabled services are designed to provide the right level of reliability and flexibility. They can be configured in two ways. They can be either zone redundant, with automatic replication across zones, or zonal, with instances pinned to a specific zone. You can also combine these approaches. For more information on zonal vs. zone-redundant architecture, see Recommendations for using availability zones and regions.
In each region where it's available, Azure API Center supports zone redundancy by default. The Azure API Center service runs in a multitenant environment on availability zone-enabled components. You don't need to set it up or reconfigure for availability zone support.
Zone down experience
During a zone-wide outage, the customer should expect a brief degradation of performance, until the service's self-healing rebalances underlying capacity to adjust to healthy zones. This isn't dependent on zone restoration; it's expected that the Microsoft-managed service self-healing state compensates for a lost zone, using capacity from other zones.
Cross-region disaster recovery in multi-region geography
Currently, Azure API Center supports only a single-region configuration. There is no capability for automatic or customer-enabled cross-region failover for Azure API Center. Should a regional disaster occur, the service will be unavailable until the region is restored.
Data residency
All customer data stays in the region where you deploy an API center. Azure API Center doesn't replicate data across regions.
