Are you looking for a dedicated server or are you looking to colocate your own server? What exactly do you mean by "private/public"? Are you planning to offer cloud hosting services to the public? If so, what platform are you planning to use?
There's no "best" datacenter for this; certain providers may be better suited to meet your specific needs, but we'd need far more information about what you're trying to do in order to make any recommendations
I am looking a company who have full setup for private cloud, I will rent private cloud and then i will provide my clients public cloud.
One kind of KMV technology also.
