Azure – Traffic Manager, Load Balancer, Application Load Balancer


Azure Traffic Manager.

The job of Azure Traffic Manager is to route traffic globally based on flexible policies, enabling an excellent user experience that aligns with how you’ve structured your application across the world. Traffic Manager has several different policies:

Latency. Direct to the “closest service”

Round Robin. Distribute across all services

Failover. Direct to backup if primary fails

Nested. Flexible multi-level policies enter image description here

Azure Load Balancer

The job of Azure Load Balancer is to direct traffic inside a region. This is combined with Azure Traffic Manager, where traffic manager routes interior to a region between virtual machines. If you combine the two you get global traffic management combined with local failover. enter image description here

Load Balancer differences There are different options to distribute network traffic using Microsoft Azure. These options work differently from each other, having a different feature set and support different scenarios. They can each be used in isolation, or combining them.

Azure Load Balancer works at the transport layer (Layer 4 in the OSI network reference stack). It provides network-level distribution of traffic across instances of an application running in the same Azure data center.

Application Gateway works at the application layer (Layer 7 in the OSI network reference stack). It acts as a reverse-proxy service, terminating the client connection and forwarding requests to back-end endpoints.

Traffic Manager works at the DNS level. It uses DNS responses to direct end-user traffic to globally distributed endpoints. Clients then connect to those endpoints directly.
