This article provides links to reliability guidance for many Azure services. Most reliability guides contain the following information: Production deployment recommendations provide guidance on how to deploy the service to meet your reliability requirements in production environments. Production deployment recommendations provide guidance on how to deploy the service to meet your reliability requirements in production environments. Resilience to transient faults 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.

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.

Resilience to availability zone failures describes how the service supports availability zones, requirements you need to meet to use availability zones, how traffic is routed and data is replicated between zones, what happens when a zone experiences an outage, zone recovery, and how to configure your resources for availability zone support. Resilience to availability zone failures describes how the service supports availability zones, requirements you need to meet to use availability zones, how traffic is routed and data is replicated between zones, what happens when a zone experiences an outage, zone recovery, and how to configure your resources for availability zone support. Resilience to region-wide failures outlines whether the service provides multiregion capabilities, requirements to use those capabilities, how traffic is routed and data is replicated between regions, the region-down experience, failover and failback support, and how to deploy custom multiregion solutions.

Resilience to service maintenance describes how the service handles planned maintenance events, including how to minimize downtime and data loss during these events. It also shows you how to configure the service to improve resilience during maintenance times.

Reliability guides by service The following table provides links to reliability guidance for Azure services. Each guide contains information about how the service supports reliability features. Some documents don't follow a single reliability guide format. These services might list more than one article that references reliability guidance.
