Cloud Computing is a Model for enabling Convenient, on-demand network access to a shared pool of configurable computing resources. Cloud technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth. Cloud is a Pay-per-Use Concept. Cache Service will be used for provide the quality of query service. Improve the cloud profit using dynamic pricing. The major goal to achieve two criteria User Satisfaction and Cloud Profit. The maximization of cloud profit given some guarantees for user satisfaction presumes an appropriate price-demand model that enables optimal pricing of query services. A novel price-demand model designed for a cloud cache and a dynamic pricing scheme for queries executed in the cloud cache. In cloud computing service cost will be increased due to demand. If the maintenance of the data in the cache which one having the lowest demand in the current situation it will be increase the cost of resource and reduce the quality of the service. For this one we have to analyze the demand factor for each data and replace the cache service data using this demand factor. That will improve the maintenance cost and built cost for the cache data.
