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 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? 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 are DevSecOps processes becoming more critical? 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: How does DevSecOps differ from traditional security approaches? A: Traditional security often acts as a gatekeeper 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 some of the biggest challenges to implementing DevSecOps in your organization? A: Some of the most common challenges are cultural resistance, gaps in skills between security and development teams, complexity of tool integration, and balancing development speed with security requirements. Q: How do DevSecOps manage compliance requirements? CI/CD Pipeline Questions Q: What exactly is a CI/CD Pipeline? A CI/CD Pipeline is an automated series of steps which takes code from the development stage through to testing and deployment.
