So far, you have learned what Azure Load Balancer is and why it is important. Azure Traffic Manager is the next level of load distribution. With Azure Traffic Manager, you are not distributing your traffic across a VNet or a set of VMs, but you are distributing the traffic across multiple Azure data centers and multiple regions across the world.

Azure Traffic Manager is one of the Azure services that provide users better and more customizable solutions to control the user traffic distribution of various service endpoints located in different data centers around the world.

Azure Traffic Manager supports various endpoints, such as cloud services, App Services, and even public IP addresses that can be associated with VMs, Load Balancers, and so on. Also, it can be used with non-Azure endpoints, either in other clouds or in your on-premises environment. Azure Traffic Manager uses intelligent DNS to specify the fulfilling endpoint.

In a nutshell, Azure Traffic Manager is Microsoft's global application delivery solution that combines end-to-end application health checks, intelligent DNS, and global load balancing into a single platform.
