PowerShell Automation and Scripting

PowerShell has become the most versatile scripting language for automating administrative tasks and managing modern IT environments. PowerShell automation allows repetitive tasks to be automated, reduces errors, and as environments grow bigger and more complex, it becomes the key to keeping control and staying efficient.

This book focuses on how PowerShell really behaves and why scripts sometimes fail in unexpected ways. To understand the nature, the book covers PowerShell scripting fundamentals like objects, the pipeline, variables, and loops before exploring Active Directory and Entra ID management. The readers will learn to automate Azure VMs using PowerShell Desired State Configuration, schedule tasks with Azure Automation Hybrid Workers, and implement remote management via JEA. The advanced modules further focus on .NET libraries, Pester unit testing, debugging, and error handling to ensure your scripts are professional and maintainable.

By the end of the book, the readers will feel confident using PowerShell in daily tasks. Scripts will be easier to understand, safer to run, and easier to maintain. Automation will become reliable instead of risky, and repetitive work can finally be reduced. PowerShell will not only be used, but it will also be understood and appreciated.
