Web Server Scalability

Applies To: Windows Server 2003, Windows Server 2003 with SP1

Internet Information Services (IIS) 6.0, running on the Microsoft® Windows®  Server 2003 operating system, includes a new architecture and new features to help your application server scale. Scaling is the ability of a system to handle increasing demands at an acceptable performance level. If an application server and the underlying infrastructure scale, the application can handle steady traffic growth, in addition to occasional peaks in traffic volumes, while maintaining good performance. If an application server and the underlying infrastructure do not scale, clients connecting to that application can experience poor response times, errors, or other problems that might ultimately frustrate end users.
