Overview of this book

Developing applications for the cloud involves changing development methodologies and procedures. Continuous integration and continuous deployment (CI/CD) processes are a must today, but are often difficult to implement and adopt. Azure DevOps is a Microsoft Azure cloud service that enhances your application development life cycle and enables DevOps capabilities. Starting with a comprehensive product overview, this book helps you to understand Azure DevOps and apply DevOps techniques to your development projects. You'll find out how to adopt DevOps techniques for your development processes by using built-in Azure DevOps tools. Throughout the course of this book, you'll also discover how to manage a project with the help of project management techniques such as Agile and Scrum, and then progress toward development aspects such as source code management, build pipelines, code testing and artifacts, release pipelines, and GitHub integration. As you learn how to implement DevOps practices, this book will also provide you with real-world examples and scenarios of DevOps adoption. By the end of this DevOps book, you will have learned how to adopt and implement Azure DevOps features in your real-world development processes.

Overview of the YAML language

YAML, an acronym for YAML Ain't Markup Language, is a human-readable scripting language used for data serialization and normally used for handling configurations definitions for applications. It can be considered a superset of JSON.

YAML uses indentation for handling the structure of the object's definitions, and it's insensitive to quotation marks and braces. It's simply a data representation language and is not used for executing commands.

With Azure DevOps, YAML is extremely important because it allows you to define a pipeline by using a script definition instead of a graphical interface (that cannot be ported between projects).

The official YAML website can be found here:

A YAML structure is based on key-value elements:

In the following sections, we'll learn how to define objects in YAML.

Scalars
