<div> </div>
<div>thank you for the links. I think Federation is the one we want to do (if possible), because we have two independent clouds we want to share which each other for use, so Federation might be the way we can go.</div>
<div> </div>
<div>I will have a look at the documents about it.</div>
<div> </div>
<div>Thank you and have a nice weekend.</div>

<div>Kind regards,</div>
