1. What is DevOps?

• DevOps is a set of practices that combine software development (Dev) and IT operations (Ops) to shorten the software development lifecycle and provide continuous delivery with high quality.

2. What are the benefits of DevOps?

·         Increased software delivery frequency and reduced time to market

·         Improved software quality and reduced defects

·         Increased collaboration between development and operations teams

·       Reduced costs and improved resource utilization

3. What are the key practices of DevOps?

·         Continuous integration and continuous delivery (CI/CD)

·         Infrastructure as code (IaC)

·         Configuration management

·         Monitoring and logging

·         Automation

4. What are some of the popular DevOps tools?

Some of the popular DevOps tools include:

·         Git

·         Jenkins

·         Puppet

·         Chef

·         Ansible

·         Docker

·         Kubernetes

·         Prometheus

·         Grafana

5. What is the difference between CI and CD?

• Continuous integration (CI) is the practice of automating the process of merging code changes from multiple contributors into a shared mainline. Continuous delivery (CD) is the practice of automating the process of building, testing, and deploying code changes to production.

6. What is infrastructure as code (IaC)?

• Infrastructure as code (IaC) is the practice of managing infrastructure using code. This allows infrastructure to be treated like software, which makes it more consistent, reliable, and scalable

7. What is monitoring and logging?

• Monitoring and logging are the practices of collecting and analyzing data about how systems and applications are performing. This data can be used to identify and troubleshoot problems, and to improve the performance of systems and applications.

8. What is automation?

• Automation is the practice of using tools to automate tasks that would otherwise be done manually. This can free up time for developers and operations engineers to focus on more complex and strategic tasks.

9. How can you measure the success of a DevOps implementation?

Some of the metrics that can be used to measure the success of a DevOps implementation include:

• Lead time to production
• Deployment frequency
• Change failure rate
• Mean time to resolution (MTTR)

12. What are some of the job titles in DevOps?
• DevOps Engineer
• Site Reliability Engineer (SRE)
• Release Engineer
• Automation Engineer
• Cloud Engineer
