Top 20 DevOps Culture Interview Question-Answer

What is DevOps?

DevOps Culture stands for Development and Operations. It is a software engineering practice that focuses on bringing together the development team and the operations team for the purpose of automating the project at every stage. This approach helps in easily automating the project service management in order to aid the objectives at the operational level and improve the understanding of the technological stack used in the production environment.

This way of practice is related to agile methodology and it mainly focuses on team communication, resource management, and teamwork. The main benefits of following this structure are the speed of development and resolving the issues at the production environment level, the stability of applications, and the innovation involved behind it.

DevOps Tools

DevOps is a methodology aimed at increased productivity and quality of product development. The main tools used in this methodology are:

  • Version Control System tools. Eg.: git.
  • Continuous Integration tools. Eg.: Jenkins
  • Continuous Testing tools. Eg.: Selenium
  • Configuration Management and Deployment tools. Eg.:Puppet, Chef, Ansible
  • Continuous Monitoring tool. Eg.: Nagios
  • Containerization tools. Eg.: Docker

What is the use of SSH?

SSH stands for Secure Shell and is an administrative protocol that lets users have access and control the remote servers over the Internet to work using the command line.

SSH is a secured encrypted version of the previously known Telnet which was unencrypted and not secure. This ensured that the communication with the remote server occurs in an encrypted form.

SSH also has a mechanism for remote user authentication, input communication between the client and the host, and sending the output back to the client.
