White paper: SharePoint 2010 for hosters (SharePoint Server 2010)
Published: May 12, 2010
This white paper provides the hosting community with an overview of Microsoft SharePoint Server 2010 and the underlying Microsoft SharePoint Foundation components, and provides detailed architectural guidance to support the multi-tenancy requirements of hosters. Although this document can be used by anyone to gain an understanding of many key features in SharePoint 2010 Products, it focuses on how these new features affect and support the hosting community.
Microsoft Project Server 2010 does not support multi-tenant environments. Do not install Project Server 2010 on a multi-tenant SharePoint Server 2010 farm. If you have Project Server 2010 installed on a farm, do not configure multi-tenancy on that farm.
