Big and Fast
"Fast" is not a word normally associated with our federal government. But that's the only word to describe how quickly the recovery.gov site was launched using SharePoint.
Converting from a platform that was not robust enough, recovery.gov took a mere ten weeks to relaunch. That's fast considering the site provides information about $787 billion in stimulus money. In addition, the site can support up to 10 million users an hour.
In technical terms, Recovery.gov uses "SharePoint for Internet Sites" as a platform, Bing for their job search, SQL to create a unified data warehouse, and FAST search for the rest of the site.
