Interview Question for DevOps Engineer

  1. What exactly is a DevOps engineer?

A DevOps engineer is someone who works with both software developers and IT workers to guarantee that code releases go well. They are typically developers who acquire an interest in the deployment and operations domain, or system administrators who develop a passion for coding and want to go into development.

A DevOps engineer is someone who understands SDLC (Software Development Lifecycle) and automation technologies for creating CI/CD pipelines.

  1. What is the significance of DevOps?

The market window for items has shrunk dramatically in recent years. We see new items virtually every day. This offers customers with a plethora of options, but it comes at the expense of intense market rivalry. Organizations cannot afford to introduce major features after a long period of inactivity. They like to offer modest features to clients at regular intervals so that their products don't get lost in this sea of competitors. Customer satisfaction is now a company credo, and it has also become the objective of any product's success.

Companies must do the following in order to accomplish this:

  • Feature deployments are carried out on a regular basis.
  • Shorter time between issue fixes
  •   Lower release failure rate
  • Quicker recovery time in the event of a release failure

 

  • DevOps culture is a very important tool for attaining the aforementioned criteria and, as a result, delivering smooth product delivery. Because of these benefits, multinational corporations such as Amazon and Google have embraced the technique, resulting in improved performance.

3. What is the function of SSH?

SSH, which stands for Secure Shell, is an administration protocol that allows users to access and operate distant servers via the Internet using the command line.

SSH is a secure encrypted version of Telnet, which was formerly unencrypted and insecure. This guaranteed that all communication with the remote server was encrypted.

SSH also includes a means for remote user authentication, input communication between the client and the host, and output transmission back to the client.

4. What exactly does configuration management entail?

Configuration management (CM) is essentially the technique of handling changes in such a way that the system does not lose its integrity over time. This includes rules, strategies, processes, and tools for analysing, managing, and monitoring change proposals, as well as keeping relevant documentation.

CM offers administrative and technical guidance to the appreciation's design and development.

5. What role does configuration management play in DevOps?

Configuration management (CM) assists the team in automating time-consuming and labor-intensive processes, therefore improving the organization's performance and agility.

It also aids in providing uniformity and enhancing the product development process through the use of design simplification, thorough documenting, control, and change implementation throughout the project's many phases/releases.

  1. In DevOps, what does CAMS stand for?

CAMS is an acronym that stands for Culture, Automation, Measurement, and Sharing. It embodies the essence of DevOps.

7.What exactly is Continuous Integration (CI)?

Continuous Integration (CI) is a software development strategy that requires developers to integrate their code into a common repository as soon as they finish working on a feature. Each integration is validated using an automated build process, which helps teams to identify issues in their code at an early stage rather than after the deployment. We can get a quick summary of the CI process based on the aforementioned sequence.

  • Developers check out code into their local workspaces on a regular basis and work on the features allocated to them.
  • When they are through working on it, the code is committed and pushed to a remote shared repository, which is managed using effective version control technologies such as git.
  • The CI server monitors changes to the shared repository and pulls them as soon as they are detected.
  • The CI server then starts the compilation of the code and, if configured, executes unit and integration test cases.
  • The results of the build are communicated to the team. In the event that the build fails, the team must focus on resolving the issue.
  1. What is the purpose of Continuous Integration?

By integrating Continuous Integration for both development and testing, it has been discovered that software quality has increased and the time required to provide new features has been dramatically decreased.

This also enables the development team to discover and correct mistakes at the outset, as each contribution to the shared repository is automatically generated and tested against the unit and integration test cases.

9.What exactly is Continuous Testing (CT)?

Continuous Testing (CT) is a DevOps phase that entails the process of running automated test cases as part of an automated software delivery pipeline with the sole purpose of receiving immediate feedback on the quality and validation of business risks associated with the automated build of code developed by developers.

Using this phase will allow the team to test each build continuously (as soon as the code developed is pushed), giving the dev teams the opportunity to get instant feedback on their work and ensuring that these problems do not arise later in the SDLC cycle. Because there are no manual intervention steps to rebuild the project and run the automated test cases every time changes are made, this drastically speeds up the developer's workflow for developing the project.

10. What are the top three DevOps KPIs?

A few DevOps KPIs are listed below:

• Shorten the average time required to recover from a failure.

• Increase The frequency with which the deployment occurs.

• A lower percentage of deployments fail.
