Key Concepts <strong>in</strong> the <strong>Virtual</strong>Center <strong>SDK</strong>• Path/Inventory• Handles• ResolvePath• GetContents• GetUpdates• PutUpdatesHow to identify whichobjects are importantand f<strong>in</strong>d and refer tothemHow to retrieve<strong>in</strong>formation, keep itcurrent and effectchange
Paths/Inventory/customPropertydatastoreeventhostperfscheduletasktemplateunknownVMvcentervmWebservice• Core objects appear <strong>in</strong>path hierarchy• Some objects appear morethan once• /vm/uuid and/vcenter/farmgrp/farm/myVM
Handles and ResolvePath• A handle is an opaque identifier for an object• Valid for the length of a session• Unaffected by object name changes• To access an object get a handle to the objectby call<strong>in</strong>g ResolvePathStr<strong>in</strong>g handle =vma.resolvePath(“/vcenter/farm/group/vm”);
GetUpdates and PutUpdates• GetUpdates returns changes to an object,synchronously or asynchronouslyUpdate delta =vma.getUpdates(vHandle,wait);• PutUpdates applies a change to an object• Example: change resources assigned to a virtual mach<strong>in</strong>eUpdate changes =vma.putUpdates(ChangeReq);

New <strong>Virtual</strong> <strong>Infrastructure</strong> API• Complete object model for virtual <strong>in</strong>frastructure• Public API = <strong>in</strong>ternal API• Available at both <strong>Virtual</strong>Center and at ESX Server hosts• Backwards compatibility mode for <strong>Virtual</strong>Center 1.xweb service<strong>VMware</strong> Web Client<strong>VMware</strong> GUI ClientThird-PartyAPIESX Server<strong>Virtual</strong> Center

Host InterfaceApplicationWebServiceESX Server• <strong>Virtual</strong> <strong>Infrastructure</strong> webservice available onESX Server hosts• Same API that <strong>Virtual</strong>Centeruses to talk to ESX Server• <strong>Virtual</strong> <strong>in</strong>frastructureservices not available• E.g., no VMotion• Returns “not supported” fault• All host capabilitiesavailable at <strong>Virtual</strong>Center• Strongly recommendleverag<strong>in</strong>g <strong>Virtual</strong>Center
Backwards Compatibility• <strong>Virtual</strong>Center 2.0 will support two WSDLs• WSDL based on new virtual <strong>in</strong>frastructureobject model• <strong>Virtual</strong>Center 1.x WSDL• No <strong>Virtual</strong>Center 2.0 features• No host <strong>in</strong>terfaceApplicationCurrent API<strong>Virtual</strong>Center1.xApplication“New” API<strong>Virtual</strong>Center2.0
Programm<strong>in</strong>g Model• Compared to Current API:• Less focus on paths and <strong>in</strong>ventory; moreobject-oriented• Hierarchy limited to VC <strong>in</strong>ventory; no /vm, /task, etc.• No resolve path; alternate ways to f<strong>in</strong>d objects• Important objects are called out asManagedObjects• Handles managed object references• GetContents/GetUpdates equivalents let youspecify the subset of properties you are<strong>in</strong>terested <strong>in</strong>
