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. 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: 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. Q: Why is DevSecOps becoming more important? Organizations need to integrate security into their development process from the beginning due to increasing cyber threats and regulatory demands. DevSecOps makes this possible by automating security tests and making security an ongoing concern. Q: What is the difference between DevSecOps and traditional security approaches.
