DevOps and DevSecOps FAQs

General DevOps Questions
Q: What is DevOps? A: DevOps is a set of practices, cultural philosophies, and tools that combine software development (Dev) with IT operations (Ops). It focuses on team empowerment, communication between teams, and automation in order to deliver high-quality software continuously.

Q: How does DevOps differ from traditional software development? Q: How does DevOps differ from traditional software development?
