SharePoint 2010 where has the SSP gone.
2010 has now removed the SSP feature as it was found difficult to use and DB intensive (too many DB’s)
It has now been replaced with Service Applications, Service Application can be related to 1 or more web application and each Service Application has it’s own DB.
This makes it easier to share resources and isolate others.
