What are the popular DevOps tool in 2021?

Agile is the most important principle for any software operation to work.  And the Development, as well as the Operations teams, should work together to the agility of the process. The Traditional approaches fail to produce continuous development and the integration process in the software development life cycle. Then the DevOps came into existence to enable the continuity for the development and integration process and also to increase the agility of the software process.  If you think of DevOps as a tool to establish the integration for development and integration process then you are wrong. Check our previous blog on What is DevOps to know the complete details on it. Today many tools were depending on these principles and many firms were using those tools for software development. Do you wanna know what are the popular DevOps tools ?. Then read the complete article on Popular DevOps tools in 2021.

The term DevOps can be described in many ways. One among them was:

DevOps is a set of principles defined to enable continuous development, continuous testing, continuous integration, and continuous deployment and continuous delivery of the software process.

Top DevOps Tools in 2021:

Today many tools that we were using were dependent on these principles. Some of them were:

1.Docker:  

Docker is a tool for containerization. This Linux –based Open-source platform focuses on containers. i.e With this tool, you can package the required software along with its dependencies as a single unit. Hence with the utilization of this tool, the user need not struggle with the depending packages everything will be taken care of by the tool itself.  This tool is portable and highly secure and allows you to use any language in it. The advantage of this tool is it allows secure packaging and deploying and also allows the running of the application irrespective of the software platform. Moreover, we can easily integrate this tool with many other tools like Jenkins, Ansible, and Bamboo.

2.Ansible:

 It is one of the most effective IT orchestration and configuration management tools in the market.  When compared with its competitors, ansible offers a software look and does not hog on your devices in the background.  This tool is primarily used for pushing the new changes within the existing system as well as configuring the newly deployed machines.  Today many IT firms were using this tool due to for lowering the cost of the infrastructure and increasing replication scalability are the two major reasons.

3.GIt:

It is another highly popular open-source DevOps tool used by industry giants like  Microsoft, Facebook, and so on.  This tool allows you to track your work development and enables you to coordinate with your team members.  This tool is easy for experimenting with because with this tool you can easily revert to the earlier versions. This tool allows developers to make rapid iterations to the code and the notification is sent immediately to the team members. Besides this tool allows the users to create branches and add those new features when they are ready. Here, you need to host the repository for work such as Git Hub.

6.Jenkins:

It is an open-source integration server, that allows you to automate the complete build of the software project. This tool is popularly used for finding the issues in the code. Besides,  it is responsible for automating the delivery pipeline and lets you test and report the changes in real-time. Due to its plugin-based ecosystem, it can easily be integrated with every other  DevOps tool.
