Impact on NFRs

This describes the impact on NFRs of the connection pooling solution pattern:

NFRs	Description
Availability	Availability will improve as we will be able to service more users with limited numbers of resources using pooling.
Performance	We can guarantee a level of performance regardless of the demand for the system.
Scalability	Scalability is improvedScalability is improved by limiting the number of connections to the system. The view on scalability is that it defines the system's ability to cope with increased load without degrading performance significantly. By imposing connection pooling patterns, we can ensure good scalability up to that limit and then prevent degradation due to overloading.
