Reliability guides by service

This article provides links to reliability guidance for many Azure services. Most reliability guides contain the following information:

• Reliability architecture overview is a synopsis of how the service supports reliability. It includes information about which components Microsoft manages and which components you manage, built-in redundancy features, and how to provision and manage multiple resources, if applicable.

• Transient fault handling describes how the service handles day-to-day transient faults that can occur in the cloud. It also describes how to handle these faults in your application, including information about retry policies, timeouts, and other best practices.

• Availability zones describe zonal and zone-redundant deployment options, traffic routing and data replication between zones, what happens when a zone experiences an outage, failback, and how to configure your resources for availability zone support.

• Multi-region support describes how to configure multi-region or geo-disaster support, traffic routing and data replication between regions, region-down experience, failover and failback support, and alternative multi-region support.

Some guides also contain information about:

• Backup support, such as who controls backups, where they're stored and replicated to, how they can be recovered, and whether they're accessible only within a region or across regions.

• Service-level agreements (SLAs) for availability, including how the expected uptime changes based on the configuration that you use.
