Now that we have reached the last chapter of the book, and have a fully functioning web app made in Flask, the final step in our development cycle is to make the app available for the world. There are many different approaches for hosting your Flask app, each of them with its own pros and cons. This chapter will cover the best solutions and guide you through situations in which you should choose one over the other.
In this chapter, we will cover the following:
- A brief introduction to the most commonly used web servers and gateway interfaces
- How to deploy on various cloud services
- How to build Docker images
- How to describe services using Docker compose
- How to describe your infrastructure using AWS CloudFormation (IaC)
- How to set up and work with a CI/CD system to easily build, test, review, and deploy our application
