Jenkins is an opensource automation server which provides 1000 plus plugins to support building, testing, deploying and automating different use-cases in industries. It is written in java with plugins built for providing continuous integration purposes. It is an server-based system that runs on servlet containers e.g Apache Tomcat.
What are the advantages of Jenkins?
- As mentioned it is an open-source tool and it has good community support.
- It is built in java, so it is supported on almost all platforms.
- It is easy to install
Let us understand some Jenkins real-time scenarios..!
1. Continuous Integration (CI):
Continuous integration allows developers to frequently integrate their code into a central repository, so instead of creating new features without ensuring the quality measurements, every change is tested against central repository.
Developers commit everyday to share mainline and every commit triggers an automated process to built and test. So this helps in detecting and fixing any fails occurred during testing or building quickly. So we can say that with Jenkins CI, it is possible to isolate problems, faster resolving capabilities and higher quality product can be achieved.
2. Continuous Delivery (CD):
Continuous delivery is the ability to make changes of all types such as new features, configuration changes, error fixes, experimenting production in a safe and efficient manner using short work cycles.
3. Continuous Deployment (CD)
Continuous deployment, also known as continuous implementation, is an advanced stage of continuous delivery that the automation process does not end at the delivery stage. In this methodology, every change that is validated at the automatic testing stage is later implemented at the production stage.
We need automation so that manually, time consuming work can be replaced with automated approach which has the capability to work efficiently with less errors.
Let us now understand how Industries are using Jenkins!!
Short Details of where Netflix uses Jenkins:
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 their artifact repository.
List of companies using Jenkins:
- Motorola Mobility (Google)
- Nokia Siemens Networks
More in the list…..!
So we can say Jenkins is almost captured the IT market with its great features and performance…
