It is important to remember that DevOps doesn’t just refer to a set of tools. It is also a mindset and a culture. DevOps requires a paradigm shift to align operations with growth and a toolchain of technologies to support collaborative transformation. DevOps Engineer’s infancy means that each firm will have a different use of DevOps.
Interview Questions for Top DevOps Engineers
To be considered for a DevOps Engineer position, the candidate must pass the Microsoft DevOps Engineer interview session. Here is an article about the Microsoft DevOps Engineer Interview.
1. DevOps: What are the main aspects?
Code for infrastructure
Continuous deployment
2. DevOps: Why do we use it?
This could be a popular DevOps interview question. DevOps allows businesses deliver more basic functionality to customers with greater efficiency and speed. DevOps’ capabilities simply show its ability to deliver seamless software delivery. Amazon and Google are two examples that have successfully implemented DevOps.
3. Describe some requirements that can be helpful in DevOps implementation.
Delegation at the top of the organization
Automated Testing
You want to see the organization change.
Software to control version.
Automated Deployment, etc.
4. What is the difference between agile and DevOps?
DevOps allows the development and employment teams to work together. This results in continuous development, integration, deployment and testing of the software, as well as monitoring its progress throughout its lifecycle.
Agile software development is a method that focuses on small, incremental, iterative and rapid delivery of software with consumer feedback. It addresses conflicts between developers and customers.
5. What are some of the most popular DevOps devices?
6. What are the benefits to DevOps?
This question should be answered by focusing on two aspects. DevOps is a combination of commercial and technical interests that demonstrates its benefits. Technological advantages include faster issue resolution, consistent software delivery, as well as overcoming complex problems. DevOps’ commercial advantages include faster delivery of features and more time to add value to the final product. DevOps’ commercial advantages are also evident in the creation of more stable operational conditions.
7. How does DevOps work?
DevOps refers to the collaboration of operations and advancement engineers throughout the project’s lifecycle, from the initial idea and development process to product releases and support. The team works together to achieve the desired goal, from design and development to measurement automation and constant integration to continuous delivery.
8. Check out the DevOps tools.
Automation plays a key role in DevOps implementation and we need tools to help us implement it. These are the main areas:
Code management
Test and Build
Release management
9. How do all the tools work together?
Developers create the code, and this source code can be maintained by Version Control System devices such as Git.
Developers can transfer this code to Git. Any modifications made to the code will be dedicated to this repository.
Jenkins extracts the code from the repository using the Git plugin, and then establishes it using tools like Ant and Maven.
Jenkins then delivers the code to the test environment. Then, Jenkins deploys the configuration management devices such as puppet deployment and provisions testing environment.
Jenkins will review the code and send it to production for deployment.
It can be controlled by devices such as Nagios after deployment.
Docker containers are a testing environment for examining the build characteristics.
10. Describe how “Infrastructure Code” is executed in AWS.
The code for the foundation will come in plain JSON format
This JSON code will then be embedded in files called templates
These templates can be extended using AWS DevOps, and then executed as stacks
11. Explain the use Test Automation in DevOps.
DevOps is more than just about devices or jobs. It’s also about people, automation, culture, and people. Continuous testing is a key role in DevOps. It involves writing scripts for software testing, making them executable to automate the examination, and releasing the software via the delivery pipelines.
12. Define Continuous Monitoring.
Agile and DevOps are about continuous development. To do that, it is necessary to continuously monitor the application performance, infrastructures, and methods. We can visualize the process and receive real-time alerts by doing continuous fascinates monitoring. We can analyze the data and make informed decisions and adapt the processes and things that are most beneficial to the business.
13. Describe the version control system.
Version Control System (VCS), software that allows software engineers to collaborate and keep track their progress. The Version Control System includes the following features:
Developers can work simultaneously
Support overwriting for each additional change.
Manage the history for each version.
14. Describe the differences between Azure DevOps Server and Azure DevOps Service.
This is a common question that DevOps candidates will encounter. Azure DevOps Services, a cloud service provided by Microsoft Azure, is extremely reliable, scalable and globally hosted. DevOps Server, on the other hand, is an on-premises atonement that’s created on a SQL Server backend.
When they have to, enterprises prefer the on-premises option.
