The number of Cloud providers are expanding their services differ from one another. These have caused difficulty for the user to choose the best services for a particular application. It is a tedious process for a user to search and select services from each provider before a chosen service can be extracted and compiled according to user preference.This process will repeat until all the desired services by the user are compiled. Then the user has to rank the providers and make a decision based on their requirements. Unfortunately, the user has to search the information again as the information frequently updated by the providers. Thus the objectives of the research are to identify providers based on user's specific applications and requirements; to build a model that user can use to decide appropriate services based on user requirements; to construct and evaluate a decision model that overcome user's difficulty to consider changing services and recommend the ranking of providers with similar services; and to enhance the decision model to grab changing services to show updated data of providers instantly. These objectives are achieved through the construction of measuring preferred service (MPS) model. Three models, Static Infrastructure as a Service (SIaaS), Dynamic Infrastructure as a Service (DIaaS) and Enhance Dynamic Infrastructure as a Service (EDIaaS) are evaluated before the MPS can be employed. The MPS model are flexible to other the cloud services and providers. The linear equation model has successfully help user in making the best decision according to their requirement and recommended providers.
