SBS 2008 is for companies with up to 75 PCs, and comes in both a Standard and Premium version. The standard version runs only on 64-bit hardware.

The premium addition of SBS 2008, which adds a 32-bit platform option, includes a database and for the first time lets users run the software on two servers. The second server runs Windows Server 2008 and SQL Server 2005 or 2008 to support business applications.

In SBS 2008, Microsoft has added tools to manage domain names and data folders, a new management console that monitors across servers and clients, customized and remotely available reports, and block-based server protection to speed backups.

EBS 2008, which is designed for companies with up to 300 desktops, includes Windows Server 2008, Exchange Server 2007, Forefront Security for Exchange Server, System Center Essentials 2007, and the new version of Internet Security and Acceleration Server now called the Forefront Threat Management Gateway. The Standard edition is 64-bit only, but the Premium version, which adds SQL Server 2008, has a 32-bit deployment option to accommodate older applications.

With both EBS 2008 versions, users will have the option to install SharePoint Services 3.0.
