Microsoft has published a new architecture poster, this time an overview of the Hyper-V Component Architecture.
This poster provides a visual reference for understanding key Hyper-V technologies in Windows Server 2008 R2. It focuses on architecture, snapshots, live migration, virtual networking, storage, and import/export. You can use this poster in conjunction with the previously published Windows Server 2008 and Windows Server 2008 R2 component posters (see http://go.microsoft.com/fwlink/?LinkId=193499 and http://go.microsoft.com/fwlink/?LinkId=179116).
