Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. Traditional load balancers operate at the transport layer (OSI layer 4 - TCP and UDP) and route traffic based on source IP address and port, to a destination IP address and port.
With Application Gateway, you can make routing decisions based on more attributes of an HTTP request, such as URI path or host headers. For example, you can route traffic based on the incoming URL.
/imagesis in the incoming URL, you can route traffic to a specific set of servers (known as a pool) configured for images.
/videois in the URL, that traffic is routed to another pool optimized for videos.
This type of routing is known as application layer (OSI layer 7) load balancing. Azure Application Gateway can do URL-based routing and more.
