ORGODEX: Service Portfolios for the Cloud

The cloud computing model offers cost effective alternatives for large distributed organizations promoting service-oriented architectures and cloud first approaches to enable a modern workplace anywhere, anytime with anyone. In this work, our objective is to validate the broader applicability of the ORGODEX model and methodology and deliver a scalable service portfolio for the cloud. First, we analyze the services of large distributed organizations, demonstrating how roles, information, responsibilities and constraints may be used to maintain service portfolios. Next, we realize the deployment of secure cloud-based service portfolios. Finally, we produce comprehensible role and responsibility matrices, demonstrating administrative scalability.

I. Introduction

Role-Based Access Control (RBAC) has been the dominant access control model for the application layer of computer systems for several decades now [11]. Cloud computing is considered one of the most prominent paradigms in the Information Technology (IT) industry today, supporting new cost effective solutions for Software as a Service (SaaS). Marrying these technologies presents interesting alternatives for large organizations whose guiding principles include service-centred design and cloud first approaches.
