The demand for the tool/ technology changes w.r.t time. An employee in the industry does have great value if the employee gets updated with the trending tool/technology today. Even though DevOps introduced over a decade, the demand for these DevOps tools gets varies w.r.t time. This DevOps suits best for all people in the IT industry. Today people taught that DevOps is a tool/ technology in the IT Industry. But if you too belong to the same category then you are mistaken. Actually
DevOps is defined as the set of principles which combines the development team as well as the operations teams to work together.
The main motto of these DevOps principles is to shorten the software development life cycle and to provide continuous delivery with high software quality. It is responsible to accelerate the application development and services at a high speed.

Since, we have got a brief idea regarding DevOps, now its time to discuss the top 10 DevOps tools to learn in 2020.
It is the Distributed Version Control System. it is the most commonly used source code management(SCM) tool. It is responsible to track the changes in your file. This tool allows you to easily coordinate with the various versions of the file systems. It is also responsible for easy integration with other popular project management software. The major advantage of this system is that we can easily roll back to the previous versions if we found the issue (or) the bug in the current file systems. Moreover, the main advantage of this file system is the developers can write the code in their own developer environment without concerning the production environment.
The following graph shows the utilization of GIT from the past one year.

It is a continuous integration server written in Java. This tool suits best for testing and reporting the changes in real-time. This tool helps developers to find and solve the bugs in your code. And finally, it is responsible for the automation of testing their build. it ensures developers were not struck up with the dread feedback loop. Moreover, it is majorly responsible for employing continuous integration (CI) automation. Besides, this tool is also capable of integrating with other several DevOps plugins. In simple words, by the integration of any DevOps tool with Jenkins, we can easily automate the entire project workflow. And we can start the integration of this tool with a simple WAR file.
The usage of this tool, over the past year, can be seen with the following diagram.
It is a container tool which uses a container to package up an application. It packages all the dependencies before shipping the complete container as the single package. Docker platform supports developers with packages. These packages usually contain all the libraries and their dependencies. It majority ensures that the packaged code contains all the prerequisites required to run. It major motto is to easy integration of the code in any production environment. Moreover, this tool supports developers to easily create, package and deploy their code through containers. Usually, containers serve as the lightweight alternative to virtual machines.
The utilization of Docker tool can be seen through the following diagram
It is an open-source, configuration management tool. It is responsible for automating the method of inspecting, delivering and operating your software across the software lifecycle. This tool does all those with platform independency. The primary application of puppet is the centralization and automation of the configuration management. This tool is developed using the Ruby language. Besides system management, this tool provides additional features like orchestration, compliance reporting and so on.
The utilization of this Puppet tools is shown in the following graph:
It is a powerful, configuration management automation tool. With this tool, we can transform the infrastructure into code. This tool is responsible for managing and configuring the multiple servers within your IT infrastructure. It ensures that all the nodes within the IT infrastructure were alive and connected. Besides chef also automatically updates the nodes in the IT infrastructure without the manual concerns. In simple words, it is responsible for maintaining all the nodes live without any downtime. Moreover, if there is a change in the server, the chef will automatically update those changes to the other nodes in the server.
Ansible is an open-source tool. This tool provides the simplest ways to automate your apps and IT infrastructure. This infrastructure includes Network configuration, Cloud deployment, as well as the creation of development environments. The major advantage of this tool is that here we can use the YAML templates. This YAML is a simple readable programming language, to enable the automatic repetitive tasks. Besides this automatic repetitive programming tasks enable the effectiveness of Ansible. Besides this tool is responsible for providing stable environments to both developments as well as the operations teams.
The utilization of Ansible tool can be seen with the following graph.
This is a powerful monitoring system. This tool enables you and you and your IT infrastructure to identify your problems. Besides this prior identification helps business to stop falling into critical problems. This is responsible for monitoring the complete IT infrastructure. This complete infrastructure includes an application, host servers as well as the business process. Moreover, this tool is also capable of monitoring and testing the plugins with the live servers. It does this process for the application periodically to ensure that the application as desired.
We can observe the utilization of Nagios with the following diagram
It is a container management tool. It allows developers to logically segregate and package the cluster of containers. Besides this tool also allows developers in automating and scheduling the deployment of containers through the master-slave node arrangement. Moreover, it is also responsible to analyze the slow slave nodes. Besides this analyzation helps to redistribution of nodes in the cluster. And finally, it ensures that all the slave nodes were connected to the master nodes.
The utilization of this Kubernetes tool can see through the following graph.
It is one of the most popular Red hat DevOps tool. It is basically an opensource hybrid application PaaS. Moreover, this tool is responsible for providing the platform as a service for developers. Its private cloud is popularly known as Open shift enterprise edition. Besides Open shift foundation includes the Security-Enhanced Linux (SHEL) and Red hat Enterprise Enterprise Linux (RHEL)
Hence with this, I hope you people got enough idea regarding the popular DevOps tools to learn in 2020. In this article, I have provided the theoretical knowledge of popular DevOps tool. You people can get the practical knowledge of these tools from real-time experts at DevOps Online Training
