DevOps and DevSecOps FAQs

General DevOps questions
Q: What exactly 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: How does DevOps differ from traditional software development? Q: How does DevOps differ from traditional software development?
