Hello Team,
Accroding to http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2016565
VDP is included with vSphere Essentials Plus and higher.
I searched but didn't come across solid information where it explains when owning certain license we don't need to buy additional license for new features / applications, etc.
I'm new to Vmware licensing hierarchy. We have Vmware vCenter Server 5 Standard license.
Please point me to an URL which contains the Vmware licensing hierarchy 
.
Thank you very much in advance.
