Everyone told me you need a native mobile app to build a health product. "Users expect polished iOS/Android experiences." "Nobody trusts a bot with health data." "Telegram is just for memes."

Kubernetes: The Platform That Keeps the Internet Running at Scale

Pipeline & Prompts | Byte size guides on DevOps, Cloud and AI When IBM acquired Red Hat, I was working as a technical seller trying to position IBM’s data science platform to clients. Our internal team was containerising CPLEX — a powerful optimisation engine used in warehouse management and supply chain applications — and running it on OpenShift. I had seen CPLEX solve complex scheduling problems in the real world. I understood inputs, equations, constraints, and outputs. But pods? Nodes? Docke
