Azure Application Gateway is essentially a load balancer for web traffic, but it also allows you better traffic control. Where classic load balancers operate on transport layer, they allow you to route traffic based protocol (TCP or UDP) and IP address, mapping IP address and protocol in the frontend to IP address(es) and protocol in the backend. Application gateway expands on that and allows us to use URLs and paths to determine where traffic should go. For example, we can have multiple servers that are optimized for different things. If one of our servers is optimized for video, then all video requests will be routed to that specific server based on the incoming URL request.
We will cover the following recipes in this chapter:
- Creating a new application gateway
- Configuring the backend pool
- Creating HTTP settings
- Creating a listener
- Creating a rule ...
