AI Data Centre
Definition
An enormous building full of specialised computers where AI models are trained and run. The tools you use in a browser don't happen on your device; they happen here, on racks of powerful chips drawing a great deal of electricity. These centres are expensive, energy-hungry, and being built at remarkable speed. They're the physical reality behind something that feels weightless and online.
Why It Matters
It's a reminder that "the cloud" is made of concrete, chips, and power bills. The energy and water these centres use is part of the honest conversation about AI's cost.
What does that look like in practice?
Ask a chatbot a question and the real work happens in an AI data centre, on racks of chips drawing serious power.
What people actually mean when they say this
When people talk about AI 'in the cloud,' the cloud is really an AI data centre: a physical building full of computers and power bills.
