PowerShell 101
Welcome to my comprehensive PowerShell 101 series! This collection represents years of hands-on experience with PowerShell automation, from managing Windows servers to orchestrating cross-platform cloud infrastructure across Azure, AWS, and hybrid environments.
My PowerShell Story
When I first started in IT operations, I was the person clicking through GUI wizards to create user accounts, configure servers, and deploy applications. Each task took 15-20 minutes of clicking through dialogs, and I was responsible for managing over 100 Windows servers. A simple security patch deployment across all servers would consume my entire day - start the process Monday morning, finish validation Friday afternoon.
I still remember the incident that changed everything. During a routine server configuration update, I had to modify the same setting across 50 servers. Twelve hours into manually clicking through each server, I made a mistake on server number 38 - wrong value in a critical setting. The server went offline during business hours, affecting 200 users. I had to roll back, fix it, and start over. That's when my senior colleague showed me a PowerShell script that could do the same task across all 50 servers in under 5 minutes, with logging and validation.
That moment sparked my PowerShell journey. I went from basic scripts to automating entire deployment pipelines. Today, I use PowerShell daily for Azure resource management, API integrations, CI/CD automation, and infrastructure orchestration. What once took days now takes minutes, and more importantly, it's reproducible, testable, and documented in code.
This series is born from real automation challenges, production deployments, and lessons learned from running PowerShell scripts that manage critical infrastructure. Every concept comes from actual implementations that solve real problems.

Prerequisites
Before starting this series, you should have:
Basic command-line experience: Comfortable using a terminal or command prompt
General IT knowledge: Understanding of files, folders, processes, networks
Problem to solve: Some repetitive task you want to automate (best motivation!)
Windows, macOS, or Linux: PowerShell runs on all platforms
No prior PowerShell experience required - we start from the beginning!
PowerShell Versions
This series focuses on PowerShell 7+ (PowerShell Core), the cross-platform version that works on Windows, macOS, and Linux. Most concepts apply to Windows PowerShell 5.1 as well, but we'll highlight differences where they matter.
Tools You'll Need
PowerShell 7+: Download from github.com/PowerShell/PowerShell
Visual Studio Code: With the PowerShell extension (recommended)
Git (optional): For version controlling your scripts
Azure subscription (optional): For cloud automation articles
How to Use This Series
Read sequentially: Each article builds on previous concepts
Type the examples: Don't copy-paste; typing helps learning
Adapt to your needs: Modify examples for your actual use cases
Experiment: Break things in a safe environment
Build real tools: Apply concepts to automate your actual tasks
My Commitment to Authenticity
Every example, scenario, and lesson in this series comes from real experience:
✅ All automation challenges are based on actual problems I've solved
✅ Code examples are patterns I use in production (sanitized for sharing)
✅ Mistakes and pitfalls are ones I've genuinely encountered
✅ Best practices come from running PowerShell in enterprise environments
You won't find "Imagine you work at Contoso Corporation" scenarios here. Just real automation knowledge that works.
