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 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? 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.
Q: What metrics matter most in DevOps? DevOps metrics that are critical include the frequency of deployment, lead time, time to recover (MTTR), failure rate and availability. These metrics help teams measure both velocity and stability.
Q: How does DevOps impact business outcomes?
DevSecOps Fundamentals
What is DevSecOps, and how does it work? 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.
