What is Jenkins?

Jenkins Introduction

In today’s world considering the era of software advancement, DevOps (Development and Operations) is an approach that incorporates with continuous testing, development, integration, deployment and supervision of software development all around the operation.

However, in the materialistic world of DevOps, continuous deployment and delivery are unfavourable to generate software products with high quality quicker than before.

Thus, among the best DevOps tools, Jenkins is known as one of them. Jenkins integrates as an open-source tool of automation codified in Java along with plug-ins shaped for Continuous-Integration.

Since Jenkins is counting amongst the best DevOps tools, its basic function is to test and generate the software programs ceaselessly by making it simpler for the programmers to initiate the modifications. Likewise making it user-friendly in order to obtain a fresh programme, besides, it also permits the continuous delivery to the software with the help of advance deployment integration and multiple testing.

Though by incorporating Jenkins training, several platforms can speed up the establishment process of software with the help of automation, it further consolidates the life cycle of developmental operations of all categories, involving testing, packaging, building, static reasoning and many more. Jenkins attains the Continuous Integration using plug-ins. With the help of Jenkins training, plug-ins enable the multiple phases of DevOps. By depending on the requirement of the developer to operate a specific tool, predefined plug-ins need to install too such as Git, Maven-2-project, Amazon-EC2, HTML publisher.

Jenkins Key Metrics

Today, in the DevOps world Jenkins can be used up to integrate all the developmental stages by the assistance of fundamental metrics. By the help of below defined key factors regarding Jenkins which is supposed to make it easier comparatively with several other best DevOps tools of Continuous Integration

• Adoption: Jenkins is functional extensively throughout the global board with the active installations estimation of approx. 150,000 along with 1.2 million subscribers’ world widely.
• Plug-ins: The interrelation of Jenkins is with more than 1000 plug-ins which empowers it to amalgamate with multiple tools, for instance, continuous testing, development, and deployment.

From the above aspects it is obvious that the world widely, Jenkins has a very high ratio of demand. Though, before diving into it, it is crucial to understand the presence of Continuous Integration with respect to Jenkins training.

What is Continuous Integration?

Currently, Continuous Integration is known for an advance practice through which the programmers are supposed to modify the initial source-code multiple times in a day or even after fix time intervals with respect to the requirements in the mutual repository.

Every single change created in the mutual repository is then assembled. However, on account of this, it is easier to identify the faults at the initial stage. On the other hand, by relying on this tool, there are many other operations too such as installing the build application on the test domain, facilitating the respective teams along with the test-build outcomes.

Continuous Integration with Jenkins

Let’s discuss the framework in which the application’s entire source-code was assembled and then integrated on the server through testing. Though this seems like a perfect scenario to initiate a software programme side by side this procedure has many defects as well, which are describing below:

• In order to achieve test results, developers must wait until all the software is formulated.
• The test results are very likely to indicate some high-end faults, and it is difficult for the programmers to check the entire program’s source-code and locate those faults.
• Most probably this drops down the implementation and deployment process of the software.
• By the constant lack of feedback on concerns such as program coding or composition (framework), structural faults, test location, and downloading file bugs considered as the factors that can decline the software quality.
• Since the entire process of CI with Jenkins training is hand-operated, increases the risk of rapid failures.

Thus, from the above-mentioned concerns, it is clear that the incorporation of this not just tended the slow deployment procedure of software but also dropped down the quality of the programme, and this leads towards the dissatisfaction of the user.

Therefore, to get the better of this chaos, it is necessary to initiate a system that would allow programmers to endlessly build and test all modification which generated in the source code. This is what known as the nature of CI.

What are the advantages of Jenkins?

• Jenkins integrates with Continuous Integration tool and works as an open source-code integrator.
• It is simple user-friendly and does not need any cost or peripheral components to install; therefore, it is very useful for start-ups.
• Simply configurable and effortless installation, so it can be easily modified and shaped as per the requirement of the work regarding continuous integrations.
• Independent platform is available on any operating systems and others as well like Windows, OS-X etc.
• Due to rich plug-ins network, Jenkins has a flexible ecosystem library that allows building, automation and deployment through the numerous stages.
• There is no deficiency of support even after the huge consumption of online groups of responsive terms since it is an easy support system and globally used.
• Programmers compose tests to identify the bugs as quickly as possible. As a result, they do not waste time on widely assimilated amalgamation.
• Bugs and defects are identified and fixed more or less in a straightaway, making the software safe to launch at any time.
• Maximum of the work containing integration is automated. So there are very fewer chances of integration problems. This protects time as well as money in the life of the software.

Drawbacks of Jenkins

• Extensions require completing all of the Jenkins basic tasks. Since Jenkins is open source-code tool, plugins might occur bugs and complications. It takes more time in installing and organizing the software before using the programme.
•  The key concern is that most Jenkins add-ons are coded by third parties. Therefore, the quality of these codes might vary, which cannot guarantee the stability of the programme.

Jenkins is anyhow identified as the most advanced CI and best DevOps tool. In future, it is expected to see how Continuous Integration with Jenkins training has got over the above-mentioned bugs.
