# Enhance Scalability Using Managed Instance Groups (Solution)

## 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%**

## Solution of Lab

%[https://youtu.be/zaKenPStM9I] 

```apache
curl -LO raw.githubusercontent.com/ePlus-DEV/storage/refs/heads/main/labs/enhance-scalability-using-managed-instance-groups-solution/lab.sh
source lab.sh
```

**Script Alternative**

```apache
export REGION=$(gcloud compute project-info describe --format="value(commonInstanceMetadata.items[google-compute-default-region])")

gcloud compute instance-groups managed create dev-instance-group --template=dev-instance-template --size=1 --region="$REGION" && gcloud compute instance-groups managed set-autoscaling dev-instance-group --region=[enter region] --min-num-replicas=1 --max-num-replicas=3 --target-cpu-utilization=0.6 --mode=on
```
