Azure Application Gateway is an Azure application delivery service that provides Layer 7 load balancing and routes web traffic to backend resources based on HTTP request properties such as host or path.
- How it is used
- Routes inbound web traffic across virtual machines according to requested application addresses.
- How deep it goes
- Defines URL-based routing and contrasts protocol balancing, but defers creation and detailed configuration to later treatment.
- Examples
- Uses llamadrama.com paths to send image requests and video requests to different virtual machines.
- What you can do after
- Evaluate whether URL-aware routing or protocol-based balancing better fits a multi-VM application.
