An XML based data representation model to discover infrastructure services

Cloud is a set of services and these services are provided to the users on demand. Different providers provide their services to the users through the cloud. With the exponential growth of the cloud services, it has become very difficult for the user to search a required service. Searching becomes still more difficult when user wishes to search a service using its functional properties. The cloud service discovery methods enable users to discover the cloud services based on the user demand. Cloud service discovery is considered as one of the important research areas because of different types and features of cloud providers, their own naming conventions and descriptions. The results of the discovery process can be improved by using a well defined repository. To improve the effectiveness of the discovery, cloud repository requires a good structure to represent the information regarding a cloud service. Information stored in the repository can also be used for selecting the services. In this paper we propose a representational model to store the description of infrastructure services using XML. The proposed data representational model also includes the semantic information.
