there is a bazillion ways to acheive the budget way is
esx --> vcenter --> vco --> vcd --> amqp --> perspectives (maybe even skipping vcd if you have limited budget but that complicates your vco side meaning you will need a skilled vco resource)
the vmware roadmap no longer includes vcd in preference of vcac for non provider companies. which I might add went GA this week.
I think that looks more like
esx --> vcenter --> vcac --> vco (haven't built it this way before might be better asking that of somebody else)
