Description

Thousands of applications nowadays are deployed in the cloud. Both frontend and backend applications require high availability, autoscaling, and fault tolerance. Because of these strategic features, Google Cloud provides you sub-services inside Compute Engine that will allow you to deploy and manage an application through the Compute Engine VMs, that will apply to the previous features. The most important ones are Instance Template and Instance Groups. With the first one, you can create an instance template that represents all the specifics that each VM running your application needs to have (such as the OS, the disk, and network); by using the second one, you can create a group of VMs and, optionally, set up autoscaling. You will create a managed instance group. It means that all the instances inside that group need to run the same instance template.

In this lab, you will create an instance template, an instance group with the autoscaling enabled, and you will then attach an HTTP load balancer to the instance group to load balance the traffic to the VM group. You will also perform a stress test to check that the autoscaling is working properly.

Learning Objectives

Upon completion of this lab you will be able to:

Create an instance template and a managed instance group
Attach an HTTP load balancer to an instance group
Perform a stress test inside a VM

Intended Audience

This lab is intended for:

Google Cloud Professional Cloud Architect (PCA) and Google Cloud Associate Cloud Engineer (ACE) certification candidates
Solutions architects who need to deploy and maintain an application architecture that requires high availability and autoscaling
Individuals who want to deep learn how to set up an application infrastructure on Compute Engine
