## Relevant notes
Most of the content of this field have a dedicated column making it not as useful as it could be.
## Notes
The usage type describes what is being used. For instances it looks like `USW2-BoxUsage:m2.2xlarge` describing in one string the region, the instance type, the generation and the size.
This could be part of a key in a [[Fact table]] (not tested yet)
