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

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 defining 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.
