Introduction to Application Gateway

Azure Application Gateway is application-level routing and load balancing service.

Application Gateway operates on OSI Layer 7 also known as the Application Layer.

Azure Web Application Firewall (WAF) policies can be attached to an Application Gateway to provide additional security.

You need to configure a Frontend

  • Private IP will create an Internal Load Balancer
  • Public IP will create a Public/External Load Balancer

You need to configure a Backend

  • You'll need to create backend pools
    • A backend pool is a collection of resources to which your application gateway can send traffic
    • A backend pool can contain
      • Virtual machines
      • Virtual machine scale sets
      • IP addresses
      • Domain names
      • App services

You need to configure Routing Rules

  • Listeners list to incoming traffic and passes it to rules
  • Rules say who should we pass data to
  • HTTP/S settings say how we should handle HTTP requests
