Infrastructure as Code and Configuration Management

Welcome, readers, to the world of Azure Cloud, Azure Resource Manager (ARM), and ARM templates. Azure Cloud is growing in leaps and bounds and has good acceptability within enterprises. Azure Cloud provides a very performance-centric, scalable, and reliable Azure Resource Manager platform for management and governance of our deployments. To create resources on Azure, ARM templates are preferred over other mechanisms because of their inherent advantages. These advantages are mentioned throughout this book.

ARM templates have become an essential skill for any serious development on Azure, and writing reusable effective ARM template is sought after by many organizations. The Azure DevOps paradigm, to a large extent, also depends on ARM templates for its automation requirements.

In this first chapter, we will cover the following...

Description

Azure Resource Manager (ARM) templates are declarations of Azure resources in the JSON format to provision and maintain them using infrastructure as code. This book gives practical solutions and examples for provisioning and managing various Azure services using ARM templates. The book starts with an understanding of infrastructure as code, a refresher on JSON, and then moves on to explain the fundamental concepts of ARM templates. Important concepts like iteration, conditional evaluation, security, usage of expressions, and functions will be covered in detail. You will use linked and nested templates to create modular ARM templates. You will see how to create multiple instances of the same resources, how to nest and link templates, and how to establish dependencies between them. You will also learn about implementing design patterns, secure template design, the unit testing of ARM templates, and adopting best practices. By the end of this book, you will understand the entire life cycle of ARM templates and their testing, and be able to author them for complex deployments.
