The VMM 2008 Client Layer
== The VMM 2008 Client Layer ==
The VMM Administrator Console, VMM Self-Service portal, Systems Center OpsMgr and Windows PowerShell cmdlets all reside in the ''Client Layer'' of the VMM 2008 architecture. The common theme amongst these components is that they all provide user interfaces for the management and monitoring of virtual machine hosts, virtual machines and the overall virtualization infrastructure. The components on the VMM 2008 Client Layer communicate with the VMM Server located in the Engine Layer using the Windows Communication Foundation (WCF) messaging platform. == The VMM 2008 Engine Layer == The VMM 2008 ''Engine Layer'' contains both the Virtual Machine Manager Server (VMM Server) component and the SQL Server database. As previously described in the chapter entitled [[VMM 2008 Components]], the VMM Server is the central component of the VMM architecture. All the other VMM components communicate with each other through the VMM Server. In addition, the VMM Server acts as the default VMM Library Server and provides an interface to the SQL Server database where configuration information about the virtualization infrastructure is stored.  A variety of protocols are used by VMM Server to communicate with the various other components in the architecture. As previously covered, WCF is used to communicate with the components on the client layer. Communication with managed Virtual Server and Hyper-V hosts and the VMM Library Server is performed using WinRM. == The VMM 2008 Managed Layer == The VMM 2008 Managed Layer contains the servers which host the virtual machines, the P2V source servers and the VMM Server Library. Transport between the VMM Server and P2V Source hosts is performed using the Distributed Component Object Model (DCOM). When communicating with SQL Server, ADO.NET is used. Finally, when managing VMware ESX Server based hosts, HTTPS is used.
