Here we go! In this chapter, we looked at the current state of Swift on the server. We started by looking at a generic microservice structure and went over what it looks like. In the process, we went from a single-server system to a multi-server system, including a load balancer.
Then, we looked at how we would run our Vapor apps on a Linux system. We went through the entire Swift installation process, followed by looking at how Docker can simplify the installation process. Finally, we took a look at how configuration should be passed to the server application and what that looks like on macOS, Linux, and Docker.
In this chapter, you learned where Swift on the server stands. You learned how to install Swift on Ubuntu and how to run it through Docker. With these skills, you can essentially run any Swift application on Linux servers.
Now that you've learned the foundations...
