Providing an Optimal Price Demand Model by Cloud Cache

摘要

Cloud computing is a practical approach to experience direct cost benefits and it has the potential to transform a data centre from a capital-intensive set up to a variable priced environment. Cloud providers trade their services on cloud resources for money. It include separate prices for infrastructure elements, i.e., disk space, CPU, I/O, bandwidth and applications deployed on the infrastructure where the service is prices as static, and provides the user for pay as per the usage. These pricing scheme does not maximize profit for cloud providers. The goal of cloud economy is to optimize user satisfaction and cloud profit. So, we propose a novel scheme that achieves optimal pricing for the services of a cloud cache which is offered by a cloud provider as an integral part of its platform-as-a-service. The goal of such a cloud cache is to provide efficient querying on the back-end data at a low cost and a dynamic pricing scheme for queries executed in the cloud cache. Data caching in a cloud is a key paradigm for improving the performance of web services in terms of both end-user latency and database load.
