In this chapter, we have deployed our code to a VPS and exposed it to the external world—first through a static IP address, and later via a domain name.
In the next chapter, we are going to look into Continuous Integration (CI) and Continuous Deployment (CD) to see how we can automate the testing and deployment steps we've introduced in the last few chapters. You'll get the chance to work with Travis CI and Jenkins, a build automation tool.
Looking further ahead, in Chapter 17, Migrating to Docker and Chapter 18, Robust Infrastructure with Kubernetes, we will use Docker containers and Kubernetes to make our deployment more scalable and reliable.
