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: How does DevOps differ from traditional software development? A: Traditional software development often separates development and operations teams, creating silos that slow down delivery. DevOps breaks down these silos, promoting collaboration, shared responsibility, and automated processes that enable faster, more reliable software delivery. Q: What are DevOps' key principles? A: The key principles include continuous integration/continuous delivery (CI/CD), automation, monitoring and observability, infrastructure as code, collaboration, and a culture of continuous improvement and learning from failures. What are the most important metrics in DevOps? A: Critical DevOps metrics include deployment frequency, lead time for changes, mean time to recovery (MTTR), change failure rate, and system availability. These metrics are used to measure both stability and velocity. Q: How does DevOps impact business outcomes? DevSecOps Fundamentals What is DevSecOps, and how does it work? A: DevSecOps integrates security practices into the DevOps pipeline, making security a shared responsibility throughout the software development lifecycle rather than a final checkpoint. Q: Why is DevSecOps becoming more important? A: With increasing cyber threats and regulatory requirements, organizations need to build security into their development processes from the start. DevSecOps makes this possible by automating security tests and making security an ongoing concern. Q: How does DevSecOps differ from traditional security approaches?
