In this chapter, you learned how to identify shared components in your solutions: pieces of code that appear not only in multiple locations but are also logical units for reuse. You learned how to use Azure Artifacts feeds for hosting packages that contain these libraries. Furthermore, you learned how to use these hosted packages to build dependent solutions using both Visual Studio and Azure Pipelines. You also learned about using universal packages to share build artifacts between Azure Pipelines and other tools that you might use for CI/CD.

With this knowledge, you will now be able to identify shared components in your solution(s). Once you have identified such a component, you will also be able to isolate it in source control, build it, and publish it to an artifact feed. From here, you can distribute it to one or more consuming solutions. Finally, you are now also capable of using Artifact feeds for sharing build artifacts between different CI/CD products.

In the next chapter, you will learn about infrastructure and configuration as code. This is one of the fundamental DevOps practices that allows you to have your infrastructure definition in source control and use that as part of your release pipeline.
