✍What is Jenkins ?
Jenkins can be termed as an automation tool that is used by DevOps teams looking to bring continuous integration into their projects. It is open-source software that is built in Java. It is used through the lifecycle of software development.
Not just in development and testing, but in deployment as well. It allows developers to integrate changes much easily into their projects. Jenkins is also used for the continuous delivery of software projects.
✍How does continuous integration work ?
Continuous integration (CI) is an integral part of the software development process. It can consist of a number of different tasks, including the use of unique functionality in the repository, feature development, and bug fixes amongst others.
A continuous integration tool, such as Jenkins, is great in identifying issues with current application sources and provides speedy response by checking the integration process with the help of automated build and test features.
The waterfall models and other such development approaches can also benefit from what continuous integration has to offer. CI often works in tandem with continuous delivery (CD) to deliver executable code to production at a much faster pace and in an automated way.
✍ Listed below are common CI practices :
- Regular code committing
2. Build staging
3. A build machine dedicated to the integration
4. Continuous feedback
5. Developer test categorization
Continuous integration can be released at whatever frequency you deem appropriate considering your project and company. So, companies that use CI have more regular releases than those that use traditional software development processes.
Early feedback and build/test automation help decrease the time it takes to go from code committed to code successfully running in production.
Automated build and test is a pre-requisite to automated deploy.
✨Time to restore service✨:
Automated pipelines enable fixes to be deployed to production faster reducing Mean Time to Resolution (MTTR)
✨Change failure rate✨:
Early automated testing greatly reduced the number of defects that make their way out to production.
This helps DevOps teams to get rid of the errors in every stage of development. It also detects problems quite early in the development process. This makes these problems less disruptive, not too complex, and easy to handle.
✍How does continuous delivery work?
Continuous delivery is a part of the software development process that enables you to go ahead with development in such a manner that we are always ready to release the software to production.
Here are a few times when continuous delivery proves additionally fruitful:
1. The DevOps team ensures that the software is deployment-ready even when feature development is under progress.
2. The software is ready for deployment throughout the software development cycle.
3. Deployment through push-button means is a reality for different versions of software to different on-demand environments.
✍How can continuous delivery be achieved ?
The first requirement is that the software should be already undergoing continuous integration. The development team should then build the executables and perform tests on them to detect errors or bugs.
Also, it is very important to test the executables in different production environments to ensure that the software is ready to be sent to production at any time. For this, having a deployment is necessary.
Automation of Jenkins allows companies to speed up their software development process quite significantly. Jenkins is capable of integrating different types of software development lifecycle processes, including building, testing, deployment, and others.
Plugins are very important for ensuring continuous integration. If you are looking to add a new tool to Jenkins, you will first have to make sure that you install a plugin for it.
✍How does Jenkins work?
Jenkins is a Continuous Integration tool. In the development process a number of different tasks including unique functionality in the repository, feature development, and bug fixes. Jenkins is useful in identifying the issue and fix it quickly.
Continuous integration has come from a programming model that is associated with the Agile methodology. However, the concept can still be applied to all those programming models that are iterative in nature.
CI often works in tandem with continuous delivery (CD) to deliver executable code to production at a much faster pace and in an automated way. Listed below are common CI practices:
- Regular code committing
- Build staging
- A build machine dedicated to the integration
- Continuous feedback
- Developer test categorization
Continuous Integration can be released at whatever frequency organization you deem appropriate considering your project and company. That is the reason the which uses CI have more regular releases than those that use traditional software development processes.
✍Advantage of Jenkins
- Jenkins is an open-source tool that is extremely easy to install and use.
- It is free and available for all the platforms like Windows, macOS, Linux, and others.
- It has great community support
- It has 1000+ plugins to ease your work.
- You can also code the plugin and provide that to the community.
- It is build using Java hence it is portable with all the major platforms.
- Due to CI/CD, it detects errors quickly and that saves the time of developer as well.
Even the minutest of change in the code could give rise to a new build. That is the reason many industry are using it.
✍Jenkins Case Study: Avoris Travel
Reinventing travel with an inventive technology platform :
A fast, simple CI/CD matters when your technology is
the driver for a new kind of travel company
👉Avoris. Reinventing Travel :
Ávoris is an innovative project, open to new ideas, driven by digital transformation, committed to excellence and quality, and the undisputed protagonist of the current tourism universe.
A great global tour operator that from Spain and Portugal with a determined spirit of internationalization, has consolidated its presence in 15 Latin American countries and extended its roots to the entire planet: from Asia, through China, to North America, with Miami as the gateway. input.
“Our infrastructure is very important because we have to be online to meet customer demand anywhere in the world,” said Alejandro Alvarez Vazquez, Sysadmin, Avoris Travel. “Our CI/CD platform is used by 200 people. The services that we build and deploy are used by thousands of potential clients and by our network of 675 own agencies located in Spain and Portugal.”
A use case for acceleration while reducing build times by more than half
Process improvement is top of mind for the ops team at Avoris. And Alejandro shared his story for one critical instance where the use of Jenkins made a big difference.
They realized their build times were on the decline, so they sought to minimize their delivery cycle times with Jenkins. The results? The team was able to speed up their CI/CD with shared volumes and more. And they were able to reduce build times more than 50%.
With over 200 developers relying on the company’s infrastructure, they needed a secure, easily customizable, and powerful CI/CD platform.
Avoris Travel, a unique travel company seeking to reinvent the travel industry, relies on an equally inventive technology platform fueled by Jenkins.
- reduced build times over 50% with the flexibility of Jenkins plugins.
- increased the speed of delivery with Jenkins Pipelines.
- Much less problematic and simple deployments for the team.
- scalable infrastructure supporting 675 agencies and over 2.8 million international consumers.
This blog provides a sound idea of how Jenkins works and how it can be used for implementing different project ideas using CI/CD and also its use-cases.
It is one of the most preferred DevOps tools these days that makes things very easy with its effective interface and plugins.
