A DevOps practitioner shares eight common mistakes people make when learning DevOps and cloud, drawn from personal experience and mentoring. The mistakes include: focusing on tools instead of concepts, learning tools in isolation without understanding how they connect, not building real projects early enough, chasing certifications over hands-on skills, being too frugal with education, relying on sandbox environments instead of real infrastructure, following roadmaps without depth or context, and failing to build in public. The core advice is to prioritize conceptual understanding, integrate tools into end-to-end projects, invest in structured learning, practice on real infrastructure, and share your work publicly to build visibility and career opportunities.
