Getting Information About a vDC
Instantiation,deployment,andoperationofavAppalltakeplaceinthecontextofavDC.TheXML
representationofavDCobjectdefinesthatcontextindetail.Forthisexercise,youneedonlytwopiecesof
informationfromthevDC:
 TheURLthataclientcanusetorequestaninstantiateVAppTemplateoperationinthevDC
 AlistofnetworkstowhichthevAppcanconnect.
Example 2‐5showsthissubsetofvDCcontents.(Foramorecompletelookatthosecontents,seeExample 3‐4

Theinformationyouneedisavailablehereintwoplaces:
 AnLinkelementcontaininganactionURL,
http://vcloud.example.com/api/v1.0/vdc/5/action/instantiateVAppTemplate.Therelattributeofthis
Linkhasavalueofadd,indicatingthatitimplementsanactionthataddsanobjecttothevDC.
 AlistofAvailableNetworksthatincludesallthenetworksownedbytheorganizationthatcontainsthis
vDC.SincewewantthisFTPservertobeaccessibleonthepublicInternet,wewillconnectthevAppto
thenetworknamedInternet.
BoththesepiecesofinformationareputtouseinExample 2

Instantiating the Template in the vDC
TocreateavAppfromthistemplate,youmustbinditsabstractresourcerequirements,suchasnetwork
connections,storageresources,memory,andCPUcapacity,toappropriateresourcesinthetargetvDC.This
bindingoperationiscalledinstantiation.Althoughaclientcanspecifythesebindingsindetail,asimple
instantiation,whichrelies
onorganizationandvDCdefaults,requiresonlyafewpiecesofinformation:
 AnameforthevAppthattherequestcreates
 TheURLofthetemplatetoinstantiate.Inthiscase,theURL(retrievedinExample 2‐4)is
