In this chapter, you learned about continuous delivery and deployment and how you can implement them using Azure DevOps. In addition to the visual release editor, you also learned about multi-stage YAML pipelines, which you can use for releasing your software to multiple stages, all of the way to production. Next, we discussed a series of strategies that you can use for releasing. You now know about blue-green deployments, using immutable servers, and different strategies for progressive exposure. You also learned how to choose between making sure you have rollback capabilities or accepting a fail forward strategy.

Then, you learned about automating release notes and documentation and how you can generate those automatically as part of your pipeline. After that, you learned about continuous deployment for mobile applications and how that differs from the delivery of web applications. Finally, you learned about the existence of Octopus Deploy, how it operates, and that it integrates with Azure DevOps.

In the next chapter, you will learn about topic dependency management using Azure Artifacts. Azure Artifacts can be used to host your own NuGet packages or to host build artifacts when you are using other products for building or releasing your application in combination with Azure Pipelines.
