Overview

• Labs are timed and cannot be paused. The timer starts when you click Start Lab.

• The included cloud terminal is preconfigured with the gcloud SDK.

• Use the terminal to execute commands and then click Check my progress to verify your work.

Challenge scenario

As a cloud infrastructure administrator tasked with optimizing compute resource management on Google Cloud, you are required to create a managed instance group named "dev-instance-group" using a pre-existing instance template named "dev-instance-template". This initiative aims to streamline deployment, enhance scalability, and ensure to use below configurations.

• Autoscaling mode : ON

• Minimum number of instances : 1

• Maximum number of instances : 3

• CPU Utilization : 60%
