THENARRATIONEvery app you use runs on someone else's computers, in buildings you could drive to, and is changed many times a day by a line of machines nobody shows you. One part at a time, from a programmer's change to the GPU hall, in plain words.
What the cloud actually is, and what happens, station by station, between a programmer finishing a change and people using the new version: what is rented, the line a change travels, the factory that builds it, and the machines themselves written down as code.
The buildings the cloud is made of: what a rack holds, where the electricity and the heat go, why a region is several buildings, how the machines inside talk, and what 'AWS is down' actually was.
How software is packed and run on rented machines: what is inside a Docker image, how Kubernetes keeps containers running, what runs when nothing is 'a server', and why the bill does not follow the work.
How a team ships changes many times a day without breaking what people use: the way of working, the robot that checks every change, why small and often is safer, how a new version meets a few users first, how engineers see inside a running system, and what happens when it breaks.
The cloud in the age of AI: why training needs tens of thousands of chips working as one, why AI data centres are built differently, how one model answers millions at once, and what an AI agent does when it is put on call.
