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 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? Q: How does DevOps differ from traditional software development? A: Traditional development of software often creates silos between the development and operations teams. This slows 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: 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
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.
