What is DevOps?
DevOps is a one-stop solution for all software engineering. From creating the software to implementing it in real-time, DevOps does all. This creates an infinite demand for excellent DevOps developers in the market. Since the platform is quite fast and effective, it is attracting the attention of many organizations that are looking to develop software solutions for their own business. Thus, here are a few DevOps interview questions that can help you crack an interview in your dream organization and grow your career.
For reliable building, testing, and releasing software faster and more reliably DevOps brings in a set of practices with facilitating the processes between the software development and the IT team. DevOps ensures that every software has the minimum systems development life cycle and sees to the fact that the software is of high quality. The core activities of DevOps can be enlisted as follows-
- Processes
- Requirements
- Design
- Engineering
- Construction
- Testing
- Debugging
- Deployment
- Maintenance
- DevOps is not only an isolated collection of processes but it also extends its scope to other approaches like Agile. DevOps and Agile are complementary to each other.
Finally, practice here the top 20+ Interview Questions on DevOps, that are mostly asked during Job Interviews.
DevOps Interview Questions
1) What is DevOps ?
2) What are the advantages of DevOps ?
3) What are the anti-patterns of DevOps ?
4) What are the advantages of DevOps with respect to Technical and Business perspective ?
- Reduce the manpower
- Reduces the complexity of the technical issues
- Resolve the technical problems quickly
DevOps not only offer the technical benefits but also provide business benefits such as:
- Stable environments for operating
- Optimum the delivering rate its features
- Enable speedier feature time to the market
- Extra time grabbled to the Add values.
5) What are the major CI tools ?
- Team City
- GitLab CI
- Buildbot
- NET
- Jenkins
- Bamboo
- Go CD
- CircleCI
6) What is the role of AWS in DevOps ?
7) How is Chef used as a CM tool ?
8) How is DevOps different from Agile/SDLC ?
Agile is the set of principles and values about how to develop software. If you have some ideas and wish to work on, then make use of agile methodology. Alternatively, DevOps is only responsible for development and deployment of the software in the reliable and safe manner. Refer the blog “Evolution of DevOps” to know more details.
9) What is the most important thing DevOps helps us achieve ?
10) Explain with a use case where DevOps can be used in industry/ real-life
Etsy is an e-commerce website, which offers peer-to-peer service. It is focused on the vintage products and manufactured items. The DevOps developers can create a complete development site within four hours thereby offering good results.
11) What are some of the DevOps best practices ?
12) Define a typical DevOps Work Flow ?
- Developers develop the source code & Version Control System tools such as Git manages it
- Developers send the code to Git repository
- Through Git plugin, Jenkins pulls the code from repository & develop it using tools.
- Configuration management tools deploy testing and Jenkins release the code
- Later, Jenkins sends the code for deployment to the production service where it is monitored continuously
- Docker is utilized as the containerization platform to offer consistent computing environment via SDLC
13) What are the major Benefits of Continuous Integration ?
- Team communication
- Improve the Your Code Coverage
- Risk mitigation
- Deploy the code to the production
- Reduce the review time of code
- Develop the stuff now and faster
- Develop the repeatable processes
- Reduced overhead
- Does not ship cracked code
14) Define ALM (Application Life Cycle Management) ?
15) What are the virtualization Tools in DevOps ?
16) What all the major Containerization Tools in DevOps ?
- Chef: It is used for configuration management purpose
- Icinga: It is specifically used for monitoring purpose.
- Docker: This particular tool is used for container management
- GitHub: A well-known tool for source control management
- Elastic search: Another interesting tool for log analytics and much more
17) What are the major Configuration Management Tools in DevOps ?
- Chef
- Rudder
- Ansible
- Puppet
- CFEngine
- Salt
- Juju
18) What all the major Provisioning Tools in DevOps ?
19) Explain the Difference between Continuous Integration, delivery, and deployment ?
There is a considerable amount of difference between Continuous Integration (CI), Continuous Delivery (CD) and Continuous Deployment (CD).
- Continuous Integration is very useful for the developers who wish to identify the bugs and resolve it instantly. With it, the developers come together to the repository.
- Continuous Delivery is suitable for the deployment and release processes. It is a right concern for the safe code releases at the possible time.
- Continuous Deployment is known for high-end automation where the deployment occurs automatically if the code has a major change.
