Code Coverage, Unit Testing, Packaging, and Deployment. In terms of
infrastructure. they are: Provisioning, Configuration, Orchestration and
Deployment.
Is there a difference between Agile and DevOps?
The Agile software development methodology focuses on the development of
software. Whereas DevOps is responsible for development as the deployment
of the software. While Agile focuses on the gaps in communication between
customer and the developers DevOps addresses the gaps in communication

tasks, so that you can build products faster and more efficiently.
Can you name some important DevOps tools?
Some of the most popular DevOps tools are:
Git: It is a Version Control System Tool.
Jenkins: Is a Continuous Integration Tool.
Selenium: Is a Continuous Testing Tool.
Puppet – Chef - Ansible: are Configuration Management Deployment Tools.
Nagios: Is a Continuous Monitoring Tool.
Docker: Is a Containerization Tool.
What is Puppet?
Puppet is among the most used open-source DevOps tools for Configuration Management and Deployment. It is used in Deploying Configuring and Managing multiple servers. It helps system administrators to control and enforce consistency across the infrastructure.
What do you know about Chef?
Chef is a powerful automation platform that converts infrastructure to code. In this tool, you can write scripts that are used to automate the processes. This feature enables chef to manage and configure multiple systems with ease.
What do you know about Version Control System?
Well, version control system is a software that helps software developers to work simultaneously and maintain a complete history of their work. It records the changes over time, so that you can revert the files or entire project, back to a previous state. It also lets you know who last modified the file that caused an issue and when. Using VCS, you can analyze how your project evolved within two versions.
What is Git? Tell me something about GitHub?
Git is an open source distributed version control system that can manage a project source code history. It is a tool that developers install locally to manage the source code. Talking about GitHub. It is a cloud based platform to which the developers who use Git can connect and upload or download resources.
What is a repository in Git?
Git is a program that tracks changes made to the file. The Git repository tracks all the changes made to the files in your project, building history over the time.

SubGit is a software tool used for migrating SVM to Git. It is stable and provides a stress free migration experience.
What is Jenkins, and what are the advantages of Jenkins?
When Jenkins has an open source continuous integration tool, which is written in Java. It accelerates the software development process by building and testing your software projects continuously. And thus, making it easier for the developers to integrate the changes to the project.
Jenkins is an open source tool with great community support, and its installation is also very easy. It provides a large numbers of plugin support. It leads to frequent new software releases. Every commit made in the source code is built and tested. So the developers need to check the entire source code. And the biggest advantages. It has built with Java, which makes it portable to all the major platforms.
What is Ansible, and why would you use Ansible?
