What is a Traffic Manager in Azure?

Azure Traffic Manager is a DNS-based traffic load balancer that enables you to distribute traffic optimally to services across Global Azure regions, while providing high availability and responsiveness.

Traffic Manager uses DNS to direct client requests to the most appropriate service endpoint based on a traffic-routing method and the health of the endpoints. An endpoint is any Internet-facing service hosted inside or outside of Azure. Traffic Manager provides a range of traffic-routing methods and endpoint monitoring options to suit different application needs and automatic failover models. Traffic Manager is resilient to failure, including the failure of an entire Azure region.

Increase application availability

Traffic Manager delivers high availability for your critical applications by monitoring your endpoints and providing automatic failover when an endpoint goes down.

Improve application performance
Azure allows you to run cloud services or websites in data centers located around the world. Traffic Manager improves application responsiveness by directing traffic to the endpoint with the lowest network latency for the client.

Perform service maintenance without downtime
You can perform planned maintenance operations on your applications without downtime. Traffic Manager can direct traffic to alternative endpoints while the maintenance is in progress.

Combine hybrid applications

Traffic Manager supports external, non-Azure endpoints enabling it to be used with hybrid cloud and on-premises deployments, including the "burst-to-cloud," "migrate-to-cloud," and "failover-to-cloud" scenarios.

Distribute traffic for complex deployments
Using nested Traffic Manager profiles, multiple traffic-routing methods can be combined to create sophisticated and flexible rules to scale to the needs of larger, more complex deployments.
