General DevOps Questions Q: What exactly 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. 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 helps to break down these silos by promoting collaboration, sharing responsibility and automating processes. This allows for faster and more reliable software development. 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 help teams measure both velocity and stability. Q: How does DevOps impact business outcomes? DevSecOps Fundamentals Q: What is DevSecOps? DevSecOps is a security practice that integrates into the DevOps Pipeline. This makes security a shared obligation throughout the entire software development lifecycle, rather than just a checkpoint at the end. Q: Why is DevSecOps becoming more important? Organizations need to integrate security into their development process from the beginning due to increasing cyber threats and regulatory demands. DevSecOps makes this possible by automating security tests and making security an ongoing concern. Q: How does DevSecOps differ from traditional security approaches?
