AWS Clean Rooms
Clean rooms for data sharing
Lets multiple companies analyze shared data together without handing raw data to one another: each party keeps its data where it is and sets analysis rules that limit which columns and query types are allowed.

- Difficulty●●●●●
- Costs money when idle?No
- Serverless
Think of it asLike two stores wanting to know how many customers they share without either one showing its customer list to the other.
When to use it
✓ Use it when
Data collaboration between parties (advertising, retail, finance) that must protect privacy.
✗ Avoid it when
Only sharing data internally between your own accounts → Lake Formation / Data Exchange.
Common uses
- Measure ad effectiveness between advertisers and publishers
- Find overlapping customers between two partners
- Train models on protected shared data
What does it cost?
- Pricing model: Charged by the compute capacity used when running queries (CRPU-hours) and ML/record-matching features if used.
