This is a good list of all the orchestrators that are out there used to provide an IaaS based cloud computing solution, that a provider might use.
Since you mentioned eNlight and GoDaddy on your list, you still need to read up on cloud computing yourself before you attempt clarifying it here.
GoDaddy, eNlight and Amazon utilize software that manages their cloud computing infrastructure (the orchestrator). It doesn't mean you are going to list them under this category since none are available to the general public (even if it costs $). These orchestrators can be simple interfaces that connect to the virtualization software's API (I suspect eNlight cloud) or as complex as GoDaddy's and Amazon's.
Another point: This confusion is what makes profit for those unscrupulous companies. Check out Parallels Virtuozzo, they now have a 'cloud' tag in its name for no apparent reason, but the software has remained the same since even before.
Everyone wants to make money with the 'cloud' :P
