Stay organized with collectionsSave and categorize content based on your preferences.
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.
This document describes the connection and parameters you can configure when
using App Design Center to create a global Cloud Load Balancing
frontend. The configuration parameters are based on theterraform-google-lb-httpTerraform module.
