The document discusses how ChronoRace, a company that provides timing services for sports events, migrated their infrastructure to Windows Azure to handle unpredictable traffic bursts during large events. Key aspects covered include identifying current infrastructure limitations, migrating the VS2003 website and SQL database to Azure, implementing auto-scaling functionality, and addressing issues with video streaming and PDF generation. The migration allowed ChronoRace to scale their infrastructure as needed for events while reducing monthly costs compared to their previous setup.
