The Global Cloud Load Balancing (Frontend) component helps you configure the public-facing elements of a load balancer. The frontend handles incoming traffic, defines routing rules, and directs requests to the appropriate backend. You can configure the following:
- Target Proxy: Terminates client connections and forwards requests.
- URL Map: Defines routing rules based on hostnames and URL paths.
- Forwarding Rule: Assigns an IP address and port to the load balancer, making it accessible.
- SSL Certificate: Manages security for HTTPS connections.
For more information, see Cloud Load Balancing overview.
This document describes the parameters you can configure when using App Design Center to create a global Cloud Load Balancing frontend.
