AZ-104- Challenge Lab 2- Configure a Virtual Machine Scale Set
AZ-104 Challenge Lab 2 – Configure a Virtual Machine Scale Set
*Lab Objectives:*
Learn to configure an Azure Virtual Machine Scale Set (VMSS).
Use load balancing and a common Linux OS disk image.
Increase the number of virtual machine instances in the scale set.
Stop and deallocate virtual machine instances.
*Lab Scenario:*
As an administrator for a company with highly elastic demand requirements for a critical client-facing application, you need to configure an Azure VMSS. This lab guides you through creating a scale set, increasing VM instances, and managing the instances effectively.
*Key Concepts and Steps:*
1. *Understanding the Lab Environment:*
The lab environment is set up in the Azure portal.
The scenario requires managing a scale set to handle fluctuating demands.
2. *Task 1: Create a Virtual Machine Scale Set:*
*Navigate to VM Scale Sets:*
Log in to the Azure portal and go to the VM scale sets section.
Create a new scale set using the following values:
*Orchestration Mode:* Uniform
*Image:* Ubuntu Server 18.04 LTS
*Size:* Standard DS1 v2
*Authentication Type:* Password
*Username:* azureuser
*Password:* [YourPassword]
*Configure Load Balancing:*
Select Azure Load Balancer.
Create a new load balancer named "webappscalesetlb."
3. *Task 2: Increase the Number of VM Instances:*
*Use Cloud Shell:*
Log into Cloud Shell in the Azure portal.
Use the existing resource group and storage account.
Run the following command to increase the number of VM instances to 3:
```bash
az vmss scale --resource-group [ResourceGroupName] --name [ScaleSetName] --new-capacity 3
```
*Verify Instances:*
Close Cloud Shell and verify that there are three running VM instances in the scale set.
4. *Task 3: Deallocate a VM Instance:*
*Deallocate VM:*
Navigate to the VM instances in the scale set.
Stop and deallocate the first VM instance.
Verify that the VM instance status changes to "Stopped (deallocated)."
*Useful Insights:*
Azure VM Scale Sets enable you to manage and scale virtual machines automatically, ensuring your application can handle varying loads efficiently.
Using load balancing with a scale set improves the availability and reliability of your applications.
*Important Notes:*
Regularly scaling and managing VM instances is crucial for maintaining optimal performance and cost efficiency.
Understanding how to configure and manage VM scale sets helps ensure your applications can handle demand changes effectively.
This session was part of my journey to master Azure's scalability features and ensure efficient management of virtual machine resources. Reviewing these concepts and steps will help reinforce my understanding and ability to apply them in practical scenarios.
