DevOps CI and CD Interview Questions

Beyond the waterfall model and Agile model, you can see DevOps is a powerful model. Its functionality is powerful, and you can find Continuous integration and continuous delivery. So the deployment you can do seamlessly.

DevOps CI CD Interview Questions

1.What is DevOps?

DevOps, Continuous Practices, or DevOps Practices! DevOps is a culture transformation! It helps to bring about change and adopt a change smoothly.

2. What is Continuous Integration?

Continuous integration most often refers to the build or integration stage of the software release process and entails both an automation component (e.g. a CI or build service) and a cultural component (e.g. learning to integrate frequently).

3. What is Continuous Delivery?

Continuous delivery lets developers automate testing beyond just unit tests so they can verify application updates across multiple dimensions before deploying to customers. These tests may include UI testing, load testing, integration testing, API reliability testing, etc.

4. What is Continuous Deployment?

It is a strategy in software development where code releases to the production automatically.

5. What is Continuous Testing?

Continuous testing is the process of executing automated tests as part of the software delivery pipeline to obtain immediate feedback on the business risks associated with a software release candidate.

6. What is Cloud Computing?

Here is the real answer for cloud computing.

7. What is the role of containers?

The containers are so light and flexible that they have given rise to new architectures of applications. This new approach consists of packaging the different services that constitute an application into separate containers and then deploying those containers through a cluster of physical or virtual machines.

8. How containers are better than virtual machines?

Containers are portable. You can move these to any cloud (AWS, AZURE, Gcloud etc.). But the virtual machine is fixed to that cloud. See the more differences here.

9. What is the difference between Continuous Delivery and Continuous Deployment?

Continuous delivery is a kind of automated testing. Whereas continuous deployment is a strategy, it pushes the code to the production automatically.

10. Why Value Stream is important?

It describes the flow of activities carried out by the development team (in the context of DevOps) to deliver values from ideas to outcomes. It means that it is important to have complete visibility in the end-to-end activities that are involved in the application lifecycle. That is called Value Stream Mapping.

11. What are the continuous practices that help culture transformation?

Cultural transformation is the application of current technologies in training products, processes, and strategies within an organization to achieve continuous improvement and innovation.

12. Why DevOps practices implementation has to be phase-wise?

DevOps practices implementation is not a short-term plan. It takes 2–5 years for culture transformation and implements DevOps practices to improve quality and to achieve faster time to market.

13. What is the importance of the maturity model?

DevOps practices implementation must be a phase-wise implementation as per the defined maturity model. It is important to perform Proof of Concepts (PoCs) and pilots before the full-fledged implementation of DevOps practices in projects.

14. How does the assessment framework help in consulting exercises?

Transformation is not an easy exercise. It is important to assess, implement, and measure this journey for Continuous Improvement and Continuous Innovations.
