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.

Multi-stage pipeline

As we explained previously, you can organize the jobs in your pipeline into stages. Stages are logical boundaries inside a pipeline flow (units of works that you can assign to an agent) that allow you to isolate the work, pause the pipeline, and execute checks or other actions. By default, every pipeline is composed of one stage, but you can create more than one and arrange those stages into a dependency graph.

The basic YAML definition of a multi-stage pipeline is as follows:

stages:  
	- stage: Build  
	  jobs:  
	  - job: BuildJob  
	    steps:  
	    - script: echo Build!  
	- stage: Test  
	  jobs:  
	  - job: TestOne  
	    steps:  
	    - script: echo Test 1  
	  - job: TestTwo 
	    steps:&...
