Skip this one unless you’re planning to or already doing things with Azure. The ARM and Bicep sections provide you with important information about how to think about your IaC (Infrastructure as Code). This book will give you the rundown on how Microsoft themselves want you to think about and work with Azure. Structuring your resources (aka Resources, Providers etc.), your Tenant, and how to make sure you’re working effectively with the tools at your disposal.

If I was about to place both my infrastructure and software stack in Azure, I’d very much like to structure it in a way that follows Microsoft’s thought-process and guidelines. It will reduce the chance of having to make difficult changes when some assumption of yours suddenly disappears.

I can also highly recommend that you read through the MSDN - Azure site if you’re serious about doing down this road.
