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 focuses on team empowerment, communication between teams, and automation in order to deliver high-quality software continuously.

Q: What is the difference between DevOps and traditional software development methods? Q: How does DevOps differ from traditional software development?
