The Cloud Is a Building
Where does an app actually live?
This film needs JavaScript and WebGL.
- The cloud isn't a cloud. It's someone else's computers, in enormous buildings, rented by the minute.
- Before, Doña Carmen would have needed her own server in the back room. Buy it, cool it, and fix it at three in the morning, in the middle of an apagón.
- Instead, she rents space in a data center: a warehouse full of computers, with its own power, cooling and guards, wired to the world by fiber.
- Inside, rows and rows of racks. Each rack holds dozens of servers. And each server is just a computer: a brain, memory, and storage.
- One big server gets sliced into many small, private computers. Her bakery gets one slice. A clinic in Ponce gets another. They never see each other.
- At Christmas, when everyone wants pan for the parranda, she rents more slices for a few days. Then she gives them back.
- These buildings sit in clusters around the world, called regions. Inside each region, several separate buildings back each other up, so one blackout doesn't take her bakery down.
- She can rent just the empty space, or a whole kitchen, ready to cook. A database that runs itself. Storage that never fills up. Even AI, paid by the question.
- The landlord guards the building. She still has to lock her own door: passwords, data, and who gets a key.
- One question left. When the app changes, a new button, a new price, how do they change it without closing the bakery?
