From financial systems and healthcare platforms to AI, e-commerce, government infrastructure and cybersecurity, the cloud is now the default operating environment for UK organisations. Demand for cloud professionals has grown rapidly, with roles spanning architecture, engineering, security, DevOps, platform operations and cost optimisation.

This article explores that gap in depth: what universities do well, what they consistently miss, why the gap exists, what employers genuinely want, and how jobseekers can bridge the divide to build sustainable careers in cloud computing.
