In the previous chapter, you learned how to use Azure DevOps pipelines for continuous integration. Due to this, you now know how to pick up a version of your sources and create artifacts that can be deployed. In this chapter, you will learn how to extend this practice with continuous delivery and continuous deployment so that you automatically deploy these artifacts to the servers or platforms your code is running on.

To do this, we will start by introducing Azure DevOps release definitions so that you can define and run the releases of your application. Next, a series of strategies will be introduced that you can use to perform deployments in a low-risk manner. Doing this makes it possible for you to automate the process of deploying new versions unattended, with a limited risk of incidents occurring. From here, we will shift our attention to automating the creation of release notes. After this, we will introduce App Center, which is used for deploying mobile applications. Finally, other tools for continuous deployment will be introduced.

The following topics will be covered in this chapter:

• Continuous delivery and continuous deployment
• Working with Azure DevOps releases
• Writing multi-stage YAML pipelines
• Implementing continuous deployment strategies
• Deploying mobile applications
• Automating release notes
• Other tools
