1. A computer program product comprising one or more computer hardware storage media having thereon computer-executable instructions that, when executed by one or more processors of a computing system, cause the computing system to operate using an architecture which governs creation of a complex resource, and wherein the architecture of the computing system comprises three tiers of user interface (UI) elements, comprising: a first tier that comprises a provisioning UI element that receives an instruction to initiate creation of a complex resource and wherein the provisioning UI element creates an edit scope used to persist data that represents a set of creation processing acts for the complex resource; a second tier that comprises a wizard UI element instantiated by a signal from the provisioning UI element in response to the received instruction; a third tier that comprises a creation processing act UI element used to generate a creation processing act form for each creation processing act in the set of creation processing acts for a given complex resource; and wherein the wizard UI element of the second tier is configured to perform the following: causes a first set of one or more creation input controls to be displayed during initiation of a first creation processing act of the set of multiple creation processing acts; saves a configuration input for the first creation processing act using the first set of one or more creation input controls; based on dependency relationships between creation processing acts in the set, determines when the first creation processing act has proceeded to a point where another creation processing act may begin; wherein the first set of one or more creation input controls is displayed as a first form created in the creation processing act UI element of the third tier, wherein some fields in the first form are populated using data from the edit scope, and wherein the first form receives and collects some user information to populate other fields in the first form; validates the user information based on a first set of persisted validation rules; once the corresponding form is completed, persists the corresponding form at the edit scope; repeats the foregoing process until all creation processing acts of the set of multiple creation processing acts are completed for the complex resource; and wherein a corresponding form for each creation processing act is added to an extendable canvas when each creation processing act is initiated, and the corresponding form is removed from the extendable canvas when the corresponding creation processing act is completed; and replacing the provisioning UI element of the first tier with a resource created status UI element that is thereafter used to select any complex resource created.
