In this chapter, you learned how to turn our cloud-based servers (and containers) into code, so they can benefit from all the methodologies we are used to using for our application projects. We solidified our knowledge of using Amazon AWS EC2 instances. You learned how to leverage the next big players in the cloud provider arena, Microsoft and Google.
