Microsoft Azure Traffic Manager is a DNS-based global traffic-routing service. It can be used to route traffic between application endpoints around the world, both in Azure and externally to Azure. Routing is based on a number of traffic-routing methods. Endpoints are monitored, so that traffic can be automatically re-directed in case of endpoint failure.
Microsoft Azure Traffic Manager allows you to control the distribution of user traffic to your specified endpoints, which can include cloud services and web sites. Traffic Manager works by applying an intelligent policy engine to Domain Name System (DNS) queries for the domain names of your Internet resources. Your cloud services or web sites can be running in the same datacenter or in different datacenters across the world.
Traffic Manager can help you:
Improve availability of critical applications – Traffic Manager allows you to improve the availability of your critical applications by monitoring your endpoints in Windows Azure and providing automatic failover capabilities when a cloud service or web site goes down.
Improve responsiveness for high performing applications – Windows Azure allows you to run cloud services or web sites in datacenters located around the world. Traffic Manager can improve the responsiveness of your applications and content delivery times by directing end-users to the cloud service or web site with the lowest network latency from the client.
Upgrade and perform service maintenance without downtime – When one endpoint is brought down, perhaps for maintenance, Traffic Manager will direct user traffic to the other available endpoints that you define in the Traffic Manager profile. This helps you to maintain and upgrade your services without downtime for clients.
