Azure Administration - Cookbook - PowerShell

A practical cookbook of complete, runnable PowerShell scripts for real Azure admin tasks—resources and tagging, identity and RBAC, VMs, networking, storage, cost management, governance, and monitoring. Includes a full migration path off the deprecated AzureRM module and Azure CLI equivalents.

Azure Administration Cookbook is a cookbook, not a certification guide. Every recipe is a complete, runnable script for something Azure administrators actually do—delivered with the permissions it needs, the output it produces, and an explanation of why it works so you can adapt it to your own estate. If you manage Azure and want to automate real tasks rather than wade through exam objectives, this book is built for you.

Every Recipe Is Complete and Runnable

There are no fragments here and no "…and adapt as needed." Every recipe follows the same practical shape: the goal in one sentence; what you'll need (roles, values, and prerequisites); the script, complete and runnable, never a fragment; what you get, showing real output so you know it worked; how it works, explaining the reasoning behind the code; and variations, pointing to the next thing you'll want to do. Substitute your own values and each recipe runs as written.

Built-In Protection Against Costly Mistakes

The most expensive mistake in Azure scripting is running a destructive command against the wrong subscription. This book builds good habits from the start—making a context check a reflex before every script—and threads that same production-minded caution through its automation recipes, so what you build is safe to run for real, not just in a demo.

If Your Scripts Use AzureRM

The AzureRM module was deprecated on 29 February 2024 and is no longer maintained or supported, with no new Azure service appearing in it since. The good news is the migration is largely mechanical—Verb-AzureRmNoun became Verb-AzNoun—but the traps are the differences that aren't just a rename. This book gives you a dedicated migration section covering how to find, convert, and test old scripts, how to use Microsoft's own migration tooling to do most of the work, and exactly which differences go beyond a simple rename.

What You'll Automate

The recipes span the full range of everyday and advanced Azure administration:

• Resources and tagging — a tag strategy worth having, creating resource groups with full tag sets, finding untagged and orphaned resources, and querying thousands of resources instantly with Resource Graph
• Identity and RBAC — assigning and auditing role assignments, creating service principals for automation, and building custom roles
• Virtual machines — creating VMs with sensible defaults, stopping payment for idle VMs, and resizing with right-sizing reports
• Networking — building VNets with segmented subnets and NSGs, diagnosing blocked traffic, and peering virtual networks
• Storage — creating storage accounts with secure defaults, sharing files with SAS tokens, and cutting cost with lifecycle rules
• Cost management — breaking down where the money actually goes and setting budgets with alerts
• Governance and policy — requiring tags at deployment time and restricting regions, SKUs, and protecting resources
• Monitoring and backup — querying logs, creating useful alerts, and backing up VMs while proving the restore works

Find Real Money in an Afternoon

Azure cost sprawl is real, and this book treats it practically. Dedicated cost recipes—breaking down spend, setting budgets, stopping idle VMs, and applying storage lifecycle rules—are designed to find real money in an afternoon. Combined with the governance recipes for tag enforcement and region and SKU restriction, they help you keep your estate both controlled and cost-effective.

PowerShell or CLI—Your Choice

The recipes are built around Azure PowerShell, but the book recognizes that many admins live in the Azure CLI too. An Azure CLI equivalents appendix helps you translate between the two, so the skills transfer regardless of which you reach for.

Suggested Paths for Your Situation

The book adapts to where you are. New to Azure automation? Read the setup and identity sections in order, then jump to whichever service you work with most. Under cost pressure? Head straight to the VM and storage cost recipes and the cost management section. Running a governance project? The resources, identity, and governance sections form a baseline. Migrating old scripts? Start with the migration section, then the recipes matching what your scripts did.

Reference Material You'll Keep Open

The appendices are built for daily use: a cmdlet reference, Azure CLI equivalents, a troubleshooting reference, a naming and tagging card, and a glossary.

Why This Book

Certification guides teach you to pass an exam; this cookbook teaches you to get real work done. With complete, runnable scripts grounded in actual admin tasks, built-in safeguards, and a clear path off the deprecated AzureRM module, it's the practical companion for anyone who administers Azure day to day. Check your context, run the recipe, and get back to work.
