A Systematic Mapping Study of Designs and Deployment Models for Cloud: Private, Public, Hybrid, Federated and Aggregated

Cloud computing is a unique paradigm that is aggregating resources available from Cloud service providers for use by customers on demand and on a pay per use basis. There is a Cloud federation that integrates the four primary Cloud models and the Cloud aggregator that integrates multiple computing services. A systematic mapping study provides an overview of work done in a particular field of interest and identifies gaps for further research. The objective of this study is to conduct a systematic mapping study of designs and deployment models for Cloud viz: private, public, hybrid, federated and aggregated. Three facets were used in the mapping process, the topic, research and contribution facets. The results obtained indicated that that there were more publications on design and service deployment in terms of tools at 11.48% and 10.86% respectively. There were more publications on service deployment in terms of methods at 6.56% and more publication on privacy in terms of processes at 4.92%.The systematic map can be interpreted in different ways based on gaps identified. This outcome will be useful to researchers, users and Cloud service providers alike. Keywords - Cloud Computing. Private Cloud, Public Cloud, Hybrid Cloud, Federated Cloud and Aggregator Cloud.
