The cloud is rented computing and storage on someone else’s infrastructure. It sounds airy, but it’s physical: your files and apps still run on real machines, just not yours, under someone else’s rules, uptime, pricing, and limits. Almost everything touches it. A hosted app, a file saved in a web product, a deployment, a call to an AI model: all of it usually runs on cloud infrastructure, often packaged in a container or running serverless.
Renting a room in someone else’s building is the everyday version. You don’t own the locks, the power, or the maintenance crew. You rent because it’s faster than building your own facility. The room may be excellent. It’s still not the same as owning the building.
Why you care
For most businesses the rental is a good trade: no racks of servers to buy, staff, and worry about. The rental also explains the risk. If the provider changes the price, changes the rules, locks your account, or makes it hard to export your files, you feel it. Know what you’re renting, what you own, where the important data lives, and how you’d leave if you had to.
