Quality of Service for Database in the Cloud

Cloud computing is a recent trend of technology that aims to provide on-demand services following a pay-peruse model. In the cloud, the service user has some guarantees, such as performance and availability. These guarantees of quality of service are defined between the service provider and user and are expressed through a service level agreement. There are many models for agreement and quality of services in cloud computing. However, most of these models are multipurpose and do not deal with data management aspects in the cloud. This paper presents QoSDBC, an approach to quality of service for database in the cloud. This approach can be used by providers to improve the quality of their services and encompasses different aspects such as response time, throughput, availability and consistency. In order to evaluate QoSDBC, some experiments that measure the quality of service are presented.
