Summary

Your application is now live on the web! In this chapter, we covered the best practices to apply before deploying your application to production: use environment variables to set configuration options, such as database URLs, and manage your Python dependencies with a requirements.txt file. Then, we showed you how to deploy your application to a serverless platform, which handles everything for you by retrieving your source code, packaging it with its dependencies, and serving it on the web. Next, you learned how to build a Docker image for FastAPI using the base image created by the creator of FastAPI. As you've seen, it allows you to be flexible while configuring the system, but you can still deploy it in a few minutes with a serverless platform that's compatible with containers. Finally, we provided you with some guidelines for manual deployment on a traditional Linux server.
