Industry Use Case of Jenkins

Development Before Jenkins

Before the advent of Jenkins, developers had to complete code testing before they could check for errors. Developers on teams, tending to work independently, each created large segments of code to add to the base code. The entire source code would be checked for errors — a time-consuming and challenging undertaking. Multiple developers would each send commits to version control, increasing the time required to identify and fix bugs. There was no iterative code improvement, and the software delivery process was slow. So for them Jenkins came to the rescue!

What is Jenkins and Continuous Integration?

Jenkins is an open source, cross-platform automation serve that helps to automate the software deployment process. As a Continuous Integration tool, Jenkins allows seamless, ongoing development, testing, and deployment of newly created code. Continuous Integration is a process wherein developers commit changes to source code from a shared repository, and all the changes to the source code are built continuously. This can occur multiple times daily. Each commit is continuously monitored by the CI Server, increasing the efficiency of code builds and verification. This removes the testers’ burdens, permitting quicker integration and fewer wasted resources.

Continuous Deployment ensures that the entire process shown above is automated. Jenkins achieves this through various plugins. Configuration is offered via both console commands and GUI interfaces. The predominant functionality of Jenkins is to execute, based on time or particular event triggers, a predefined set of steps. Jenkins observes the execution of these steps and in case of a failure, terminates the process. Jenkins notifies build successes and failures.

What are the Jenkins Features?

Jenkins offers many attractive features for developers:

Easy Installation

Jenkins is a platform-agnostic, self-contained Java-based program, ready to run with packages for Windows, Mac OS, and Unix-like operating systems.

Easy Configuration

Jenkins is easily set up and configured using its web interface, featuring error checks and a built-in help function.

Available Plugins

There are hundreds of plugins available in the Update Center, integrating with every tool in the CI and CD toolchain.


Jenkins can be extended by means of its plugin architecture, providing nearly endless possibilities for what it can do.

Easy Distribution

Jenkins can easily distribute work across multiple machines for faster builds, tests, and deployments across multiple platforms.

Free Open Source

Jenkins is an open-source resource backed by heavy community support.

Industries Using Jenkins


Netflix is a streaming service that offers a wide variety of award-winning TV shows, movies, anime, documentaries, and more on thousands of internet-connected devices. So Netflix greatly uses Jenkins for its use case. Once a line of code has been built and tested locally using Nebula, it is ready for continuous integration and deployment. The first step is to push the updated source code to a git repository. Teams are free to find a git workflow that works for them.

Once the change is committed, a Jenkins job is triggered. Netflix’s use of Jenkins for continuous integration has evolved over the years. They started with a single massive Jenkins master in their datacenter and have evolved to running 25 Jenkins masters in AWS. Jenkins is used throughout Netflix for a variety of automation tasks above just simple continuous integration.

A Jenkins job is configured to invoke Nebula to build, test and package the application code. If the repository being built is a library, Nebula will publish the .jar to our artifact repository. If the repository is an application, then the Nebula ospackage plugin will be executed.


Topdanmark is a leading Danish insurer who chose Jenkins as the “de facto” product to build their CI/CD platform.


Balancing the needs of DevOps modernization and cloud migration while maintaining legacy systems.


A highly-configurable CI/CD platform which allows for automation and ease of development.


  • 100% automatic creation of Jenkins instances
  • the ability to release and deploy an artifact whenever, wherever
  • software developers focused on developing software rather than operations
  • smaller monoliths and containerization

Topdanmark has two Jenkins setups. They have two sets of systems, legacy and CI/CD. In their legacy setup, they have test, integration, release, and production environments. In their CI/CD setup, they have a non-production and a production environment.

“We used Jenkins because almost everyone knows what Jenkins is and how to use it. It is the ‘de facto’ product to use in our world. And it’s extremely configurable.” said DevTools engineer Jon Brohauge.
