What Is a Data Centre?
A data centre is a highly secure building that houses thousands—or even hundreds of thousands—of computer servers.
These servers store, process, and distribute enormous amounts of digital information.
Every time you:
- Watch Netflix
- Search Google
- Use ChatGPT
- Access online banking
- Stream music
- Shop online
- Use Microsoft 365
- Save photos to the cloud
…your information is being processed somewhere inside one or more data centres.
Think of them as the factories of the digital economy.
Instead of manufacturing automobiles or steel, they manufacture information processing.
