Cardspace Geneva), and Windows Identity Foundation (formerly known as the Geneva
Framework). Why use this new system? Identity drives very important aspects of an
application such as identifying who the user is (authentication), what permissions the
user is granted (authorization), and how the application interacts with the user
(personalization). All applications work with identity today, but usually in their own way.
Often, integrating these applications can be a very difficult process.
Claims-based identity provides a common way for applications to acquire identity
information from users inside their organization, in other organizations, and on the
Internet. Identity information is contained in a security token, often simply called a
token. A token contains one or more claims about the user. Think of it as metadata
about the user that stays with them throughout their session.
Claims-based authentication opens the door to great possibilities in SharePoint Server
2010. Greater flexibility for authenticating users against multiple repositories within the
same Web application and a more personalized experience based on the claims or
information about the user provided in the token.
Service Applications Conclusion
Service applications are a modular set of services that will provide SharePoint
administrators with needed flexibility to provide only necessary functionality to Web
applications within the farm or the enterprise. They can be scaled out to achieve
maximum performance or combined into groups to maximize resources. Because each
one can be assigned and administered separately, SharePoint administrators will be able
to delegate as appropriate.
Health and Monitoring
Microsoft® SharePoint® Server 2010 includes a number of features that provide the
administrator with tools for monitoring the health and performance of the SharePoint
farm. These features are categorized into the following groups: diagnostics, reliability
and monitoring, and reporting. The following table shows the various categories and
their corresponding features.
