What is the purpose of Azure Traffic Manager, and how does it work?

Azure Traffic Manager is a cloud service that assists companies in spreading out the incoming visitors to different places, like Azure Virtual Machines, Azure Web Apps, and external websites. It does this to make sure the application is always available, runs well, and can handle lots of users. It decides where to send traffic based on where users are, how fast the connection is, and if everything is working properly.

Here’s how Azure Traffic Manager works:

  1. Endpoints: First, you configure one or more endpoints that will receive incoming traffic. These endpoints can be Azure VMs, Azure Web Apps, external websites, or any other internet-facing resource.
  2. Traffic Routing Method: Next, you choose a traffic routing method, which determines how Azure Traffic Manager distributes incoming traffic across the endpoints. There are several traffic routing methods available, including:
  • Priority: Traffic is sent to a primary endpoint, and if it’s unavailable, it’s sent to a secondary endpoint.
  • Weighted: Traffic is distribute across endpoints based on a weighted distribution.
  • Performance: Traffic is sent to the endpoint with the lowest network latency.
  • Geographic: Traffic is sent to the endpoint that is closest to the user’s geographic location.
  • Multi-Value: Traffic is sent to multiple endpoints at the same time.
  1. DNS Configuration: After configuring the endpoints and traffic routing method, you update the DNS configuration for your domain name to point to the Azure Traffic Manager profile. The Azure Traffic Manager profile acts as a DNS alias for your domain name, and it routes incoming traffic to the appropriate endpoint based on the configured traffic routing method.
  2. Monitoring: Finally, you can monitor the health and performance of the endpoints using Azure Traffic Manager’s monitoring and health probes. If an endpoint becomes unavailable or unresponsive, Azure Traffic Manager can automatically remove it from the traffic routing pool until it becomes available again.
