The following table lists key elements in Microsoft® Provisioning Framework's architecture.
| Element | Description |
|---|---|
| Groups | Categories of users. Microsoft Provisioning Framework has five groups: MPFAdmins, MPFAuditors, MPFServiceAccts, MPFClientAccts, and MPFTrustedUsers. |
| Microsoft Provisioning Framework | Platform for building, deploying, managing, and extending hosted services running on Microsoft Windows operating systems. |
| Namespace | Mechanism that Microsoft Provisioning Framework uses to link providers and procedures with MPF. Namespaces can also be used to group procedure calls. Every namespace procedure has an input schema and (optionally) an output schema. The input schema optionally validates data supplied to the procedure. The output schema defines the format for data returned by the procedure. |
| Procedure | Blueprint for executing the steps of a provisioning request. A procedure can be a declaration of a provisioning action executed by a provider or a sequence of calls to other MPF procedures. |
| Providers | Mechanisms to execute requests. A provider is a COM object with one or more procedures that automate specific tasks. The provider is implemented as a .DLL file with a corresponding namespace registered in the configuration database. |
| Provisioning Engines | Transaction coordinators that route real-time provisioning requests to called providers. The engine provides a framework for integrating multiple actions into a single transaction. The engine maintains contextual information and transaction state. |
| Requests | Instruction to the Microsoft Provisioning Framework to execute a provisioning task. |
| Provisioning Queue Manager Service | Mechanism to coordinate requests queued for later processing by a provisioning engine. Examples of queued requests include operations that typically require a lot of time to complete and batch operations that process many records simultaneously. |
| Transaction Logs | Record of the real-time state of all executing transactions running in provisioning engines. Transaction logs are implemented as Microsoft® SQL Server databases. |
| Transactions | Series of activities associated with a request and used to manage transaction state and rollback information. |
