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 emphasizes team empowerment, cross-team communication, and automation to enable continuous delivery of high-quality software at scale.
