In this liveProject, you’ve joined up with a company whose intranet is at least 15 years out of date. Your boss wants to update to a modern, microservices-based architecture that runs in the Cloud using Kubernetes. The IT team has kicked off this project with a new UX design for your web applications—but there’s a catch. Those old web apps have business processes built into them that can’t be rewritten from scratch. Instead, you’ve decided to transform these legacy applications into RESTful web services. You’ve chosen the old employee profile Java web app as your first conversion project, supplying a RESTful API that can provide read-and-update capabilities to other services and applications. Your challenges in this liveProject will include reviewing and modernizing the legacy app with Spring Boot and RESTful APIs, Dockerizing the app to run in a container environment, deploying it onto Kubernetes, and then testing that it’s working properly.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
This liveProject is for intermediate Java developers, who are familiar with the basics of Enterprise web development. You will need the Java JDK, Maven, and MySQL installed on your workstation. To begin this liveProject, you will need to be familiar with:
- Basic Java
- Basic Spring
- Basic Docker
- Basics of containerization
- Basics of DevOps
- Basics of web development
