vCloud vs vCould Director - which is intended for what usage?

[Bk Lau]

I  have a quick question:

Seems that you have some vCloud vs. vCloud Director implementation(in labs
package); so the natural question that comes to mind is :

Why the duplicates?. Isn't vCloud Director an implementation of vCloud
APIs?.

So which should or intended to be used in what usage context?.

Just want some clarification.

Thanks,

BK
