Migration of a Java business application to Docker as well as startup within a Kubernetes cluster

The challenge was to analyze the existing Java business application, containerize it using Docker, set up a new Kubernetes cluster, and deploy the application with all its environments and interfaces there and get it up and running.

Another task was to manage the transition from a monolithic application structure to a containerized environment.

In addition, there was a goal to implement a CI/CD pipeline to enable fully automated deployment in a test environment. In addition, the productive operation of the platform could not be impaired by the migration project.

Realization

After the new Kubernetes cluster environment was designed, the changeover was accomplished with the use of Rancher. The Java business application was containerized using Docker. In addition, a CI/CD pipeline was introduced to enable automated deployments. This improved the efficiency of the development team and enabled faster and more reliable provision of software updates. Migrating the application to Docker and Kubernetes has significantly improved the flexibility and scalability of the application. By moving to containerized deployment, changes to the application can now be made more efficiently and with virtually no downtime. In addition, the introduction of a CI/CD pipeline has significantly increased the speed and efficiency of the deployment process.

BITS took on all IT roles during implementation, from conception to project management and individual development to operation of the finished solution. Continuous further development is also carried out by BITS.
