Conclusion : Models as Web Endpoints

The Python ecosystem has a great suite of tools for building web applications. Using only Python, you can write scalable APIs deployed to the open web or custom UI applications that interact with backend Python code. This chapter focused on Flask, which can be extended with other libraries and hosted in a wide range of environments. One of the important concepts we touched on in this chapter is model persistence, which will be useful in other contexts when building scalable model pipelines. We also deployed a simple application to Heroku, which is a separate cloud platform from AWS and GCP.
