Background & Objective: Organizations have started evaluating business applications
which are on hosted model. Organizations need not to focus on choosing the deployment model or
buying the hardware or setup infrastructure instead they are choosing business application which are
easily available on SaaS model or platform model. Organizations are analyzing the adoption of
Cloud Computing service models due to reduced the load of IT overheads and to bring agility in deploying
applications. An organization should have the scientific way to choose and identify the right
service model to fulfill its IT and business needs.
Methods: This research paper focuses on proposing a decision model with the help of Analytic Hierarchy
Process (AHP) and benefit-cost- opportunity-risk (BCOR) analysis to select the appropriate
service models i.e. SaaS or PaaS or IaaS to fulfill the business needs. It suggests a range of key attributes
which act as building blocks of the model based on Analytic Hierarchy Process (AHP). The
model will provide the benefits, cost, opportunity and risks of cloud computing services for the three
service models of cloud computing.
Conclusion: This study results will be useful for organizations to adopt cloud computing service
model which suites the requirements as well as rapid deployment of the applications.
