Is Jenkins the best CI/CD tool in the market?

November 15, 2017

by Analysts

Jenkins, the leading opensource tool for Continuous Integration (CI) and Continuous Deployment (CD) processes, is integral to the DevOps world.

Continuous Integration is a process of building and testing the code whenever the developer pushes the code to source control. Continuous Deployment is the process of deploying the code to multiple environments without any human intervention, thus reducing the time to deliver.

There are several CI/CD tools in the market like Jenkins, TeamCity, Travis CI, Bamboo, CircleCI, and VSTS.

However, Jenkins tops this list of CI/CD tools being used in the market because of several reasons.

Advantages of Using Jenkins

Open Source: Being an opensource project, it has 482 contributors, 542 releases and 9,348 stars on GitHub (as on the day this blog was posted), which is quite high in the opensource world. It provides quick and efficient community support to its users.

Cross-Platform Integration Tool: It runs without depending on an operating system (Windows, Linux, and Mac).

Extensible: It integrates with almost all DevOps tools through plugins. It provides over 1000+ plugins to perform various build and deployment tasks. Users can also create their own plugins if required.

Command Line Interface: This makes this tool extensive, enabling users to write scripts that can perform any action. It can be handy for SysAdmins.

It also provides an API that triggers a job when an event arises. Jobs can be run in this tool as per the desired schedule. It can be integrated with SCM (Source Control Management), CM (Configuration Management) tools and containerization tools which form a full DevOps cycle.

Apart from being opensource, this tool is also popular for features like ease of installation and configuration with numerous plugins, and the master-slave concept which helps users distribute the jobs across multiple systems.

It has also taken a leap towards improving its UI/UX. Known as the “Blue Ocean”, the new Jenkins project is the most intuitive approach to understand a key concept of this tool – the PIPELINE. It reduces clutter and provides clarity in what the user is doing. Blue Ocean gives newbies a jump-start towards becoming professionals in applying the pipeline concept in their workflows.

Apart from providing the option of notifying users about the build status through email, Twitter, etc., Jenkins is also going multilingual with i18n support, which will help users across the globe.

It can be secured by creating users and roles. Every user is assigned a set of roles to be restricted to a particular task. It also provides a plugin to integrate with AD (Active Directory) using LDAP (Lightweight Directory Access Protocol).

Summarizing Jenkins’ Features

To sum it up, here is what this tool can do:

  • Trigger a build (manual, periodic, poll SCM)
  • Get the source code from a repository
  • Automatically build and test
  • Generate reports (static code analysis, code coverage)
  • Notify (Email, Twitter, Jabber, Google Calendar)
  • Deploy to servers

Tools in the DevOps arena are vulnerable to challenges due to the fast-changing nature of this space as well as the continuous inflow of newly developed tools. But the versatility of Jenkins is cementing its position as one of the best CI/CD tools, at least for the near future.
