Goal-Based Cloud Broker for Medical Informatics Application: A proposed goal-based request and selection strategy

Medical informatics application nowadays combines computer technology and clinical medicine to improve health care, medical education, and medical research. For many years, people debated about existing processes in collecting patient's important data with a great deal of work to discover, select, and analyze the information. To reduce treatment delay and errors in retrieving data, resource broker technology can be used to provide good indexing metadata. Existing resource broker are mostly applied in grid computing and widely used in business environment. In this paper, we proposed a goal-based cloud broker as a solution to improve the current broker technology. Our solution is based on the concept of goal which enables users in defming required resources and to optimize the usage of resources in the cloud. Several contributions by this research include enhancing resource brokers by using goal-based request to maximize resources allocation within the cloud environment and to assist user in selecting the best suitable resources in cloud by minimizing user intervention in resources discovery.
