DevOps and DevSecOps FAQs

General DevOps Questions
Q: What is DevOps? DevOps is an integrated set of practices, cultural ideologies, and tools which combine software development (Dev), with IT operations (Ops). It emphasizes team empowerment, cross-team communication, and automation to enable continuous delivery of high-quality software at scale.

Q: What is the difference between DevOps and traditional software development methods? Q: How does DevOps differ from traditional software development? A: Traditional development of software often creates silos between the development and operations teams. This slows down delivery. DevOps helps to break down these silos by promoting collaboration, sharing responsibility and automating processes. This allows for faster and more reliable software development.

Q: What are the key principles of DevOps? A: The key principles include continuous integration/continuous delivery (CI/CD), automation, monitoring and observability, infrastructure as code, collaboration, and a culture of continuous improvement and learning from failures.

Q: What metrics matter most in DevOps? DevOps metrics that are critical include the frequency of deployment, lead time, time to recover (MTTR), failure rate and availability. These metrics help teams measure both velocity and stability.

Q: What are the business benefits of DevOps? A: DevOps practices lead to faster time-to-market, improved product quality, increased customer satisfaction, better resource utilization, and enhanced ability to respond to market changes and security threats.

DevSecOps Fundamentals
What is DevSecOps, and how does it work? DevSecOps is a security practice that integrates into the DevOps Pipeline. This makes security a shared obligation throughout the entire software development lifecycle, rather than just a checkpoint at the end.
