ABSTRACT (maximum 200 words) Cloud computing portrays a new model for providing IT services over the Internet. In cloud computing, resources are accessed from the Internet through web-based tools. Although cloud computing offers reduced cost, increased storage, high automation, flexibility, mobility, and the ability of IT to shift focus, there are other concerns—such as the management, organization and structure of content on the cloud—that large organizations should consider before migrating to the cloud. This thesis presents an overview of Model View Controller (MVC) architectural pattern and describes how the pattern can be applied to the cloud for content management. The MVC architecture is proposed in this thesis because it divides the aspects of a document into three parts: a model, view and controller, thus allowing elasticity, portability, and interoperability for document objects. The thesis presents a case study to illustrate how MVC can be used to facilitate document collaboration and content management in the cloud, and examines existing document standards to assess their readiness in supporting the MVC document architecture. 14.
