Components of Azure Front Door

1. Frontend hosts:

Frontend hosts represent the entry points for incoming traffic to Azure Front Door. They define the domain names or custom hostnames through which users access web applications or content.

2. Backend pools:

Backend pools contain the backend endpoints to which traffic is routed by Azure Front Door. They can include Azure web apps, API endpoints, virtual machines, or any publicly accessible HTTP/S endpoint.

3. Routing rules:

Routing rules define the logic for routing incoming requests to backend pools based on criteria such as URL path, host header, or query string parameters. They allow organizations to implement custom routing and load balancing strategies tailored to their specific requirements.

4. Health probes:

Health probes monitor the availability and health of backend endpoints by periodically sending requests and evaluating responses. They enable Azure Front Door to dynamically adjust traffic routing based on the health status of backend endpoints, ensuring high availability and reliability for applications.
