Cloud Computing Basics Still Trip Up Experienced Engineers

The global cloud market crossed $900 billion in annual spend in 2025, according to Gartner's infrastructure services forecast. That number would've sounded absurd a decade ago. Today it's just Tuesday. What's strange: despite that scale, cloud computing basics remain widely misunderstood — even among experienced engineers. Teams over-provision. Architects pick the wrong service model. Finance gets sticker shock. The fundamentals haven't changed, but the consequences of getting them wrong have grown dramatically alongside the spend. This matters specifically in 2026 because the cloud landscape has matured past the "just lift and shift" era. AI workloads, edge deployments, and multi-cloud strategies have layered serious complexity onto what were once straightforward decisions. Getting cloud computing basics right isn't a beginner's exercise anymore. It's a strategic differentiator. The core argument: understanding cloud computing at a structural level — not just surface-level definitions
