SharePoint 2010 includes a fundamental architectural change from the previous version with the introduction of “Service Applications”. This new architecture has extremely broad and deep consequences for SharePoint practitioners. Unfortunately Service Applications thus far have been poorly explained and documented, and already there are many myths surrounding them. This “In a Nutshell” article is an attempt to distil the core elements down to brass tacks. It is intended primarily for architects and administrators planning their farm topologies, but will also be useful for anyone working with SharePoint 2010.
