</div></div>Capacity planning not falling under Compute's umbrella is news to me,<br>
are you referring to Gantt and scheduling in general? Perhaps I don't<br>
fully understand the full extent of what 'capacity planning' actually<br>
<div>is.<br>

</div>I don't see how Climate reserves resources is relevant to the user.<br>

</div>Unfortunately that doesn't clarify things for me.<br>
<br>
>From the user's point of view what is the benefit from making a<br>
reservation in the future? Versus what Nova supports today, asking for<br>
an instance in the present.<br>
<br>
Same thing from the operator's perspective,  what is the benefit of<br>
taking reservations for the future?<br>
<br>
This whole model is unclear to me because as far as I can tell no<br>
other clouds out there support this model, so I have nothing to<br>
compare it to.<br>
