Existing tenant model might not be enough. A given organization writes several application. App Factory is used for the full life cycle of the application, including dev test, QS, Performance test etc. Because of this, one application should not affect the performance of other applications. Note that we used stratos tenancy to satisfy this request. This (isolation) is the reason why we are keeping each application as a separate tenant. We used stratos tenancy is not visible to users. This fact is only internal implementation detail. We could have some something else ( I don't know what) to achieve the isolation requirement.
Now, we have many such organizations. This is the real "user" level tenancy. Dimuthu's userstory is about this. The question is how to satisfy above two requirements at the same time. IMO, we need a hierarchical tenant model to achieve both. Or, we have to have a "project" or "application" concept in the platform.
