From DWS4 a Cloud Account is a collection of Users and Environments.
A Free Trial Account initially has one Environment and one User, which is the person that starts the trial, and that first user is given an Administrator role.
The Account is managed by the Administrator, who can invite new users and assign them roles.
An Account has a quota, which is the maximum number of pages that can be generated in a calendar month. The Account quota can be divided and allocated to any available Environments.
Accounts can be used globally and work in all available Processing Locations.
