In this chapter, we learned how to deploy the Spring Boot application. We went through the different deployment options of the Spring Boot application and deployed the application to Heroku. Next, we deployed our React frontend to Heroku using the Heroku Buildpack for create-react-app, which makes the deployment process fast. Finally, we used Docker to create containers from our Spring Boot application and MariaDB database. In the next chapter, we will cover some more technologies and best practises that you should explore.
