Traditional data center management involved manual action for every configuration change, using system administrators and operators. In comparison, infrastructure as code facilitates housing infrastructure configurations in standardized files, readable by software that maintains the infrastructure’s state. Configuration Management is often performed using tools such as Ansible, Puppet, Chef, and SaltStack, which automate the process and make it easier to manage complex software systems at scale. Managing software development remotely can be a challenge, and it is even more complex when you are working with a DevOps team.

Q13. How do you setup a script to run every time a repository receives new commits through push?

The employer will want to make sure that you know exactly which job you are signing up for, its expectations, and the skills required – and not confuse it with a related but different concept.

Using role-specific questions and tasks alongside other trusted methods like soft skills assessments and Culture Add tests is the best way to improve your quality of hire.

  • Functional testing is a type of testing that verifies if a system meets the specified functional requirements and works as intended.
  • This necessitates leveraging auto-scaling features to dynamically adjust resources based on real-time demands, in the context of cloud resources.

  • Additionally, you can also use the “Thin Backup” plugin or other backup plugins to automate the backup process and ensure that you have the latest backup available in case of any failure.

It is a systems engineering process that focuses on establishing a product’s consistency and maintaining that level of efficiency throughout its lifecycle. DevOps provides flexibility in development and operations, focuses on timeliness and a quality product, and makes improvements based on internal feedback. The interviewers want to make sure you can differentiate between software development methodologies. They’re testing your core competency, so an incorrect answer here will raise concerns.

This phase involves understanding the project properly for the ultimate work goal of its participants.

Employ automated security testing tools to scan code for vulnerabilities during the build phase. Implement code analysis and static application security testing (SAST) to identify and rectify security issues in source code. Version control is crucial in DevOps because it allows teams to manage and save code changes and track the evolution of their software systems over time. Some key benefits include collaboration, traceability, reversibility, branching, and release management. Configuration Management (CM) is a practice in DevOps that involves organizing and maintaining the configuration of software systems and infrastructure. It includes version control, monitoring, and change management of software systems, configurations, and dependencies.
