With SharePoint 2010, Shared Service Providers are dead and the new Service Application model takes over. A brief note on the challenges with SSP and overview of Service Applications is below.
Challenges with SSPs in MOSS 2007
- Web applications were limited to consuming from single SSP
- Deploying SSPs was difficult
- SSPs were tied to a single farm
- SSP management and troubleshooting was difficult
- Shared services were not extensible
- Service applications replace the MOSS 2007 SSP
- The service application framework is now in MSF2010
- Many-to-many relationship between web applications and service applications
- Service applications offer improved scalability, load balancing and fault tolerance
- Service applications can be consumed across farms
- Windows Powershell support
