deployment,power‐on,orboth.

Instantiate a vApp Template
AvApptemplatespecifiesasetoffiles,suchasvirtualdisks,thatthevApprequires,andasetofabstract
resources,suchasCPU,memory,andnetworkconnections,thatmustbeallocatedtothevAppbythevDCin
whichitisdeployed.InstantiationcreatesavAppfromthefiles
specifiedinthetemplate,andallocates
vDC‐specificbindingsfornetworksandotherresources.(Thesebindingsareadvisory;theydonotguarantee
thattheresourceswillbeavailablewhenthevAppisdeployed.)Instantiationisaprerequisitetodeployment.
Inthemostcommonusecase,aclientinstantiatesavApp
templateandimmediatelydeploysit.
