What are ECE Limits

1) Max Bandwidth 

2) Max Storage

3) Max Concurrent Users

There's a bit of a comparison between the plans here https://magento.com/trial/plans-comparison but I've never heard Magento talk in these terms. Your best bet is probably to get in touch with the Magento Cloud sales team directly.
