Configure a regional Cloud Load Balancing frontend in Application Design Center
Stay organized with collectionsSave and categorize content based on your preferences.
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.
This document describes the connections and parameters you can configure when
using App Design Center to create a regional Cloud Load Balancing
frontend. The configuration parameters are based on theterraform-google-regional-lb-httpTerraform module.
Component connections
The following table includes the components that you can connect to a regional
Cloud Load Balancing frontend, and the resulting updates to your application
and its generated Terraform code.
