Modeling an IaaS Broker Based on Two Cloud Computing Reference Models
Due to its rapid growth, short history and lack of regulation, eliciting the requirements for an information system broker in an IaaS Cloud Computing context can be a challenging task. Reference models such as the NIST Cloud Computing Reference Architecture and The Open Group Cloud Ecosystem Reference Model stand as recognized models in this domain. Additionally, Use Case models allow representing the process view of a system and can be considered as an adequate elicitation method for the cloud. Mapping these processes on both reference models may allow for a Cloud Computing suitability check for a proposed solution. Along these lines, we present the results of our work on an industrial project for a cloud broker platform in an IaaS service model. This approach allows for a feasibility and consistency check of the elicited system, pointing some incompletions and flaws, but also important differences in the reference models.
