Load Balancer

Official Documentation

Service Description

All data traffic from the public Internet that aims to access Azure resources must pass through the Azure load balancer, which processes various protocols (e.g., http, https, smtp) and where appropriate forwards calls to the required Azure resources after performing security checks. The load balancer checks the availability of the resources on a regular basis and ensures that calls are sent only to available resources. For multilayered applications, within a Virtual Network an internal load balancer can also be configured between the individual layers.
