Agile focuses on making the developers and development cycles more efficient, while brings the operations team into play to enable continuous integration and continuous delivery.

2. Why do we need DevOps?

DevOps is important because it’s a software development and operations approach that enables the faster development of new products and easier maintenance of existing deployments.

3. What are the important business and technical benefits of using DevOps?

DevOps engineers can exploit real-time data into the performance of their systems to quickly understand that the impact of application changes. And resolution times are faster because team members don’t need to wait for a different team to troubleshoot and fix the problem.

4. Can you name some of the most-used DevOps tools?

The most-used DevOps tools are:

Jenkins.
Docker.
Phantom.
Nagios.
Vagrant.
Ansible.
GitHub.

5. What is Selenium used for?

6. What do you understand by Puppet in DevOps?

Puppet is a cross-platform client-server based application used for configuration management. It works on both the Linux and Windows platforms. It uses a declarative approach to automate updates, installations, and other tasks. This feature allows the software to configure those systems using files called manifests.

7. What do you understand by anti-patterns of DevOps?

An anti-pattern is a pattern that you use to fix a short-term problem at the expense of your long-term goals. The insidious thing about anti-patterns isn’t that they don’t work or fail outright, but that they work in the short term while causing the long-term failure and pain.

8. DevOps has something called CI. What is it and what is its purpose?

Continuous integration is the practice of automating the integration of code changes from multiple contributors into a single software project. It’s a primary DevOps best practice, allowing developers to frequently merge code changes into a central repository where builds and tests then run.

9. More often than not we hear shift left in DevOps. What is it?

Shift Left is a practice intended to find and prevent defects early in the software delivery process. The idea is to improve quality by moving tasks to the left as early in the lifecycle as possible. Shift Left testing means testing earlier in the software development process.

10. What does CAMS in DevOps stand for?

CALMS is a framework that assesses a company’s ability to adopt the DevOps processes, as well as a way of measuring success during a DevOps transformation. The acronym was coined by Jez Humble, co-author of “The DevOps Handbook,” and stands for Culture, Automation, Lean, Measurement, and Sharing.

11. What are the several KPIs used to gauge DevOps success?

The several KPIs used to gauge DevOps success are:

Deployment frequency.
Change failure rate.
Mean Time to Recovery
Lead time.
Change volume.
Defect escape rate.
Customer tickets.
DevOps Resources.

12. In your opinion, what are the major benefits of implementing DevOps automation?

The major benefits of implementing DevOps automation are:

Elimination of recurring action items enabling staff to focus on value addition.
Increased deployment rate for new software releases.
Reduction of ongoing operational cost.
Establishment of standard ‘error-free’ work environments.

13. What do you understand by containers?

A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another.

JavaScript. While Python is more flexible, JavaScript adds significant value to the DevOps Environment.
Ruby.
Perl.

16. Explain how DevOps is helpful to developers?

Developer patterns and technologies are very useful in the operations side. Being able to pull in things such as the infrastructure as code, version control, static analysis, and code reviews allows DevOps to be more efficient and more effective, often using the same programming languages.

17. List out some popular tools for DevOps?

The popular tools for DevOps are:

Git. Code, Build.
Gradle. Build.
Selenium. Test.
Jenkins. Build, Test, Deploy.
Puppet. Deploy, Operate.
Chef. Deploy, Operate.
Docker. Build, Deploy, Operate.
Kubernetes. Build, Deploy, Operate.

18. Mention at what instance have you used the SSH?

I utilized SSH to switch into a virtual computer and operate on the manual board Besides this, in addition to promoting protected the authenticated correspondence between two unauthenticated servers across an unreliable infrastructure, I have utilized it to funnel into the device.
