The Regional 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.
For more information, see Cloud Load Balancing overview.
This document describes the parameters you can configure when using App Design Center to create a regional Cloud Load Balancing frontend.
