Azure Application Gateway
Azure Application Gateway
Azure Application Gateway is a web traffic (OSI layer 7) 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.
- Application Gateway can make routing decisions based on additional attributes of an HTTP request, for example URI path or host headers.
