An FBM model of ISO cloud computing architecture

Abstract

With the ever-changing dynamic Information and Communications Technology environment and the new shared deployment options for computing, a paradigm shift has occurred, which enables ubiquitous and convenient computing on a pay-as-you-go basis. Access on demand has become available to networks of scalable, elastic, self-serviceable, configurable physical and virtual resources. This paper updates the previous paper that addressed early ISO Committee Draft (CD) work on Cloud Computing by ISO ISO/IEC JTC1 SC38 (in collaboration with ITU-T SG13/WP6 for Cloud Computing), and models the full and expanded ISO Cloud Computing Reference Architecture and Service Level Agreement (SLA) using Fact Based Modeling (FBM) methodology. FBM has allowed us to distill the concepts, relationships and business rules - thereby capsulizing the Cloud Computing standards to enable understanding, and also exposing the strengths and weakness of the models, and thus allowing for identification of any gaps towards furthering the ISO standard.
