Reporting Services 2008 additional features, other than SQL Server Reporting Services 2005
SQL Server Reporting Services has been introduced in 2000 version but not catched within the user environment until the Reporting Services 2005 has been rolled out. In this regard administering a Reporting Services installation requires that you know how to perform routine maintenance tasks for server components, and how to manage the content and ongoing operations of the report server.
Reporting Services components include Report Server Web service, for background processing applications, which handle scheduled operations and report delivery and a report server database on SQL Server. All of these included on Server side and what it takes to manage them, the membership in the local Administrator group on the report server computer. If your installation includes server components that run on remote computers, you must have administrator permissions on those computers if you want to manage those servers over a remote connection. Obviously DBA permissions must have SYSADMIN privilege and if SSRS is on domain controller then the DBA login must be domain administrator.
So how about scaling up the Reporting Services solution using 2005 and 2008, more to know what has been changed between these 2 major versions in SQL Server arena. Refer to Scaling Up Reporting Services 2008 vs. Reporting Services 2005: Lessons Learned link for more information.
