Comprehensive 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 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?
