DevOps and DevSecOps FAQs

General DevOps Questions
Q: What 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: How does DevOps differ from traditional software development? A: Traditional software development often separates development and operations teams, creating silos that slow 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: 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.

Q: Why is DevSecOps becoming more important? A: With increasing cyber threats and regulatory requirements, organizations need to build security into their development processes from the start. DevSecOps makes this possible by automating security tests and making security an ongoing concern.

Q: How does DevSecOps differ from traditional security approaches? Traditional security is often a gatekeeper that comes at the end of development. DevSecOps integrates the security process throughout the development cycle, automating testing and making security a shared responsibility for all team members.

Q: What are the main challenges in implementing DevSecOps? A: Common challenges include cultural resistance, skill gaps between development and security teams, tool integration complexity, and balancing security requirements with development speed.

Q: How do DevSecOps manage compliance requirements?

CI/CD Pipeline Questions
