An economic model for client-side cloud caching service

An economic model for client-side cloud caching service Cache-as-a-Service (CaaS) benefits cloud computing users from personal to corporate levels. One of the important factors contributing to the success of CaaS at the corporation level is much lower expense compared to performance received. However, careful consideration must be given when choosing CaaS to achieve cost-effectiveness. Thus, the service model of CaaS allowing custom-made SLA will be extremely useful. Currently, almost all available CaaSes are server-side. This paper presents the flexible economic model of client-side CaaS as an early attempt in the field. The model considers both CapEx and OpEx as well as fixed costs and variable costs of the client-side CaaS.
