Assignment: Managing Azure Virtual Machines with Azure CLI in PowerShell

Scenario:

As a DevOps engineer, you need to automate the management of Azure virtual machines (VMs) based on their tags. Your task is to write a PowerShell script that uses the Azure CLI (az cli) to retrieve a list of all VMs in a subscription, check their tags, and perform specific operations based on the tags.

Requirements:

1. Use the az vm list command to get a list of all VMs in the subscription.
2. For each VM, check the value of a specific tag (e.g., Environment) to determine the environment it belongs to (Development, Staging, or Production).
3. Perform the following operations based on the environment tag:

• For VMs in the Development environment, stop the VM.

Introduction

I am a seasoned IT professional with a strong background in cloud technologies, particularly in Azure. Over the years, I have successfully led several migration projects, helping organizations transition from on-premise environments to the cloud. My expertise lies in assessing applications for cloud readiness, optimizing resource utilization, and ensuring high availability and scalability in cloud-native deployments.

Migrations

In my role, I have played a key part in migrating organizations from on-premise data centers to the Azure cloud. This involved assessing the existing infrastructure and applications, developing a migration strategy, and executing the migration plan with minimal downtime. I have also focused on optimizing resource utilization and cost management during these migration projects, ensuring that the organizations benefit fully from the cloud environment.

Containerization/Kubernetes

Containerization offers several benefits in the context of Azure cloud-native migra

Class Summary: Introduction to PowerShell, Linux Comparison, Terraform Folder Structure Creation, and PowerShell Loops

In this class, we covered the basics of PowerShell, compared it with basic Linux commands, and explored the creation of a structured folder hierarchy for Terraform using PowerShell scripts with nested foreach loops. Additionally, let's delve into how loops work in PowerShell, with a focus on the foreach loop, by explaining different iterations:

1. Introduction to PowerShell 💻:

• PowerShell is a powerful scripting and automation framework for Windows operating systems.
• It provides access to system management functions and data stores via .NET, COM, and WMI.
• PowerShell commands (cmdlets) are used to perform various tasks and follow a verb-noun naming convention (e.g., Get-Process, New-Item).
• PowerShell scripts are written in .ps1 files and can be executed to automate tasks and manage system resources.
