Cloud Service Elasticity
In the service provider view, cloud service elasticity is the ability to increase or decrease the amount of system capacity (for example, CPU, storage, memory and input/output bandwidth) that is available for a given cloud service on demand, in an automated fashion. This gives their customers the perception of unlimited capacity. From the consumer and RTI perspectives, cloud service elasticity is an automated means to increase or decrease a specific service capacity in response to increasing or scheduled demand changes.
