Comprehensive DevOps and DevSecOps FAQs
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: 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.

What are the most important metrics in DevOps? DevOps metrics that are critical include the frequency of deployment, lead time, time to recover (MTTR), failure rate and availability. These metrics are used to measure both stability and velocity.

Q: What are the business benefits of DevOps?

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.

Q: Why are DevSecOps processes becoming more critical? Organizations need to integrate security into their development process from the beginning due to increasing cyber threats and regulatory demands. DevSecOps enables this by automating security checks and making security a continuous concern.
