Azure Application Gateway
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.
An Application Gateway is composed of Frontends, Routing Rules and Backends:
- Frontends, chose an address type:
- Private IP will create an Internal Load Balancer
- Public IP will create an Public/External Load Balancer
2. Backends, create Backend Pools
- A backend pool is a collection of resources to which your application gateway can send traffic.
- A backend pool can contain, VM scale sets, IP addresses, domain names, App service
3. Routing Rules are composed of listeners, Backend targets, HTTP Settings
a) Listeners “listens” on a specified port and IP address for traffic that uses a specified protocol.
- If the listener criteria are met, the application gateway will apply this routing rule.
- There are 2 types of listeners:
- Basic: Forward all requests for any domain to backend pools
- Multi-site: Forward request to different backend pools based on host header and host name
- Request are matched according to the order of the rulse and the type of listener
- Add your basic listeners last otherwise it will capture all request
3.2 Backend target choose where a route should go either Backend Pool or Redirection
- To create a rule for Backend Pool you need to create HTTP Setting
- Defines how we want to handle cookies, connection draining, port request time out and more.
