Open Source Devops Tools We Love In 2019

Hello techies, this is my second article on DevOps.  In this article, I am going to explain about DevOps tools which are used to automate the stages.

I hope you understood the concept of DevOps and its significance from my first article on DevOps. If you haven’t gone through my previous article, I will let you know in short about DevOps.

Devops is a software development strategy which bridges the gap between the Dev and the Ops side of the company.  It means it will helps you to reduce the communication gap between the development team and operations team and increase the productivity.

DevOps is a software development approach which involves continuous development, continuous testing, continuous integration, continuous deployment and continuous monitoring of the software throughout its development life cycle.

Now let us know which DevOps tools are used to automate the stages.

Continuous Development Tools:

  1. GIT
  2. SVN
  3. JIRA
  4. Confluence

Continuous Testing Tools:

  1. Building Tools
  2. Maven
  3. Ant
  4. Gradle

Testing Tools

  1. Selenium
  2. JUnit

Continuous Integration Tools

  1. Jenkins
  2. Codeship

Continous Deployment Tools

  1. Docker
  2. AWS
  3. Puppet
  4. Chef
  5. Ansible
  6. Kubernates

Continous Monitoring Tools

  1. Datadog
  2. Splunk
  3. Nagios.

For source code management we have GIT, SVN, JIRA and Confluence. These tools help us in maintaining the code throughout the development life cycle. Different revisions of the code can be stored and if we want to rollback on any changes then we can just call that previous version of the code and deploy to production. These tools will track the changes in files and coordinating work on those files among multiple people. It is primarily used for source-code management in software development and also used for keep tracking the set of files.

JIRA is an issue tracking product developed by Atlassian which allows bug tracking and agile project management.

For building we have tools like Maven, Ant and GradleMaven build automation tool used for Java Projects. It is developed by Apache Software Foundation. Ant is also a software tools which is used for automating the build processes and it is developed by Apache Software Foundation. Gradle is an open source build automation system that builds upon the concepts of Apache Ant and Apache Maven and introduces a groovy based domain specific language. They help you package your code into executable files which can then be produced into the testing environment. Then for continuous testing we have tools like Selenium and Junit.

For continuous integration we have a very popular tool called Jenkins. So if you are a software developer you will know what Jenkins is? If not, don’t worry I will explain about Jenkins.

Jenkins is an Open Source automation tool written in Java. It is build for Continuous integration purpose. It provides Continuous Integration services for software development, which can be started via command line or web application server. Jenkins is an open source and it can be downloaded and installed with free of cost. Continuous integration means that you can test changes and then test that changes with other changes.

The next stage is continuous deployment stage. For this we have tools like Puppet, Chef, Saltstack and Ansible.  All these tools are open source configuration management tools. As and when the code is tested and ready it is push it to production or the non-developer machine at this stage.

And finally for continuous monitoring we have tools like New Relic, Datadog, Splunk and Nagios. These tools will help us to monitor our servers closely and check the health of the system. Anything can happen to your server it anytime right, so it’s important they are monitored proactively rather than reactively. Will they also improve productivity and increase the reliability of the systems, quite possibly save lots of money and support costs.


DevOps tools plays a prominent role and they are required to automate the stages from continuous development to continuous monitoring. So many tools are available for different programming languages and different platforms. Based on your requirements you have to choose them and automate the system.
