Azure Traffic Manager is the Microsoft solution for georedundant traffic routing. It is available in each Azure region, and it provides transparent load balancing for services that coexist in different Azure regions, non-Microsoft clouds, or on premises. It provides the following features:

• Flexible traffic routing
• Reduced application downtime
• Improve performance and content delivery
• Distributed traffic over multiple locations
• Support for all available cloud solutions (private and public clouds)

As you can see in the following diagram, Azure Traffic Manager is a flexible solution for traffic routing, and can point to each target that you need in your application design:

Incoming traffic is routed to the appropriate site using Traffic Manager metrics, and if a site is down or degraded, Traffic Manager routes the traffic to another available site. You can compare Traffic Manager to an intelligent router that knows the origin of the traffic and reroutes the requests to the nearest available service.
