Scalability

Visual Studio .NET 2003

Scalability is the capability to increase resources to yield a linear (ideally) increase in service capacity. The key characteristic of a scalable application is that additional load only requires additional resources rather than extensive modification of the application itself.

Although raw performance makes a difference in determining the number of users that an application can support, scalability and performance are two separate entities. In fact, performance efforts can sometimes be opposed to scalability efforts.
