Open Stack

hello ,everyone ,thanks for your reply to my previous question. Acturally i wanna know whether the open-source IaaS management platform is suitable for providing IaaS service for our customers. Before that ,we have to do some basic tests about function and performance and capability. Now I really do not know what i should do for the basic test? for example, we have to verify the performance of the platform, maybe we will simulate 1000 more users to simultaneously send the request of resource, we will know whether this platform will be broken down or not. That is the one of the most important for us . just like the test mentioned before, what else should i have to do to verify. 
many thanks
