This project used a Hierarchical Decision Model (HDM) approach by dividing the model hierarchies into Mission, Objectives, Goals, Strategies and Actions, also called MOGSA. The fundamental criteria used for assessment are: Innovation Factor, Technological Factor, Usability Factor and Economic Factor. These four primary evaluation criteria were further divided into seven subcriteria: Complexity, Compatibility, Security, Architecture, Usefulness, Ease of Use and Cost. These criteria were evaluated using a pairwise comparison method. Four cloud computing platforms were considered for the project: Amazon Web Services, Google Cloud Platform, IBM Bluemix and Microsoft Azure. A group of experts was used to measure and compare results of the HDM. This group includes application developers working in different domains and had been using cloud computing platforms. The range of inconsistency recorded was between 0.02 and 0.04, whereas the disagreement between the judgments was 0.055. Despite individual responses by some of the evaluators, Amazon Web Services was the preferred cloud computing platform, thus making the HDM a better methodology to quantify and counterbalance all individual preferences while making complex decisions.
