~ Jean Paul ~ Leave a comment

Load Balancers helps to distribute the Network Traffic across different servers or applications.  Thus high response systems are maintained.

In Azure there are 3 types of Load Balancers.

Azure Traffic Manager

This is an External Global Load Balancer which determines the User’s Location and Redirect to the Closest Region of Deployment.

Azure Application Gateway

This is Layer 7 load balancing.  Here the incoming traffic is distributed using the cookie, url-routing rules etc.  There will be backend pool websites behind a single application gateway.

Azure Load Balancer

This is Layer 4 load balancing.  There are 2 types under this category:

  • External Load Balancer for routing requests to Frontend Public IP Addresses
  • Internal Load Balancer for routing request to Backend Private IP Addresses
