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: 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 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 are used to measure both stability and velocity.

Q: How does DevOps impact business outcomes? 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? A: DevSecOps integrates security practices into the DevOps pipeline, making security a shared responsibility throughout the software development lifecycle rather than a final checkpoint.
