Introduction to Azure Load Balancer


Load balancing has always been one of the most important and straightforward methods for scaling up infrastructure.

The load balancer mainly distributes the traffic across a set of servers to enhance the responsiveness and the availability of VMs.

In a nutshell, the load balancer receives the traffic from the client and redistributes it across a set of servers. As a result, it ensures the following:

  • High availability of the service for which you use Azure Load Balancer, as the client connects only to an online server that has no issues
  • Flexibility of adding or removing backend servers behind Azure Load Balancer

Azure Load Balancer is not different. It is a layer 4 load balancer that distributes the traffic across either VMs or cloud services; and, if one of the VMs becomes unavailable, the traffic gets redirected to another VM.
