DevOps 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 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 the key principles of DevOps? 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: What are the business benefits of DevOps? DevOps practices result in faster time-to market, improved product quality and customer satisfaction. They also lead to better resource utilization and enhanced response to security threats and market changes.

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.
