In SharePoint 2010 Shared Service Providers (SSP's) are replaced by Service
Applications. Services are no longer combined into a SSP. They are running
independent as a service application. The service application architecture is
now also built into Microsoft SharePoint Foundation 2010, in contrast to the
Shared Services Provider (SSP) architecture that was only part of Office
SharePoint Server 2007.
A key benefit here is that all services are installed
by default and there is no SSP setup.
Additional improvements for the service application model
include:
• The services architecture is extensible, allowing
third-party companies to build and add services to the platform.
• Services
are managed directly in Central Administration (rather than a separate
administration site).
• Services can be monitored and managed remotely.
•
Services can be managed and scripted by Windows PowerShell™.
• Shared
services communications take place over HTTP(S). Shared services do not directly
access databases across farms.
• Most new services are built on the Windows
Communications Framework. They have optimization built into their protocol,
using binary streams instead of XML for data transfer. Test results show
improvements in network throughput with this change.
