Overview
Google Cloud Application Load Balancing is implemented at the edge of Google's network in Google's points of presence (POP) around the world. User traffic directed to an Application Load Balancer enters the POP closest to the user and is then load balanced over Google's global network to the closest backend that has sufficient capacity available.
Cloud Armor IP allowlist/denylist enable you to restrict or allow access to your Application Load Balancer at the edge of the Google Cloud, as close as possible to the user and to malicious traffic. This prevents malicious users or traffic from consuming resources or entering your Virtual Private Cloud (VPC) networks.
In this lab, you configure an Application Load Balancer with global backends, as shown in the diagram below. Then, you stress test the Load Balancer and denylist the stress test IP with Cloud Armor.
Objectives
In this lab, you learn how to perform the following tasks:
Create HTTP and health check firewall rules
Configure two instance templates
Create two managed instance groups
Configure an Application Load Balancer with IPv4 and IPv6
Stress test an Application Load Balancer
Denylist an IP address to restrict access to an Application Load Balancer
