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 breaks down these silos, promoting collaboration, shared responsibility, and automated processes that enable faster, more reliable software delivery.

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 help teams measure both velocity and stability.

Q: What are the business benefits of DevOps?

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.
