Service Insurance: A New Approach in Cloud Brokerage

In cloud service domain, an acceptable standard of quality of service (QoS) must be maintained for subscribed services. The performance measurement of those cloud services is based on the satisfaction of customers with respect to the pre-defined QoS. Deviation of QoS as mentioned in SLA results dissatisfaction among users. A large numbers of business entities and consumers are involved in this service delivery process. In business environment, guaranteeing the QoS and establishing the service contracts are essential. However, for the service providers, it is challenging to maintain the QoS at run-time. Moreover, even if it is maintained, additional cost may be needed. Sometime a categorization among the consumers (premium or ordinary) is also required due to the limitation of the resources. Thus, the service management for ensuring the delivery with desired QoS at least for the premium consumers is necessary. This paper proposes a novel methodology termed as service insurances, which is incorporated into the service broker as a new module. The proposed concept is expected to ensure customer's satisfaction in context of a business application domain.
