Azure Traffic Manager is a DNS-based traffic load balancer. This service allows you to distribute traffic to your public-facing applications across the global Azure regions. The Weighted traffic-routing method allows you to distribute traffic evenly or to use a pre-defined weighting; the higher the weight, the higher the priority. The weighted method is useful in scenarios like Gradual application upgrade, application migration to Azure, and Cloud-bursting for more capacity.

The weighted method is useful in scenarios like gradual application upgrades by giving a percentage of traffic to route to a new endpoint and for gradually increasing the traffic over time to 100% or for cloud-bursting for more capacity by quickly expanding an on-premises deployment into the cloud by putting it behind a Traffic Manager profile.

In this hands-on lab, you will understand how weighted traffic-routing works by configuring application endpoints across two different Azure locations.
