Hi Fred, 

I had already read this article about the Git flow and policies to create a model of development.  Indeed, I read a lot of articles before posting this question here, but Git concepts are not exactly the problem. I believe Its more related to how Ensemble enviroment works versus Git structure.
Anyway, I appreciated your interest and contribution.

Hello Guillaume,

really intersting... this architecture seems much more appropriate for the solution we're looking for. The issue now is about licensing and its impact ($$) in our team... 

I'll do some research and verify if it's practicable.

Thank you!

Good to hear that, Fred. Probably we'll need some testimonies if this license stuff leads to budgeting changes. :-/
