The main objective for this project is to design an architecture that’s able to offer a technological platform capable of providing an inter-institutional or federate service (between organizations) using a cloud-computing paradigm to deliver opportunistic resources. To accomplish the main purpose of this project, two technologies and types of implementation available were studied and evaluated, in order to generate an architectural model through an iterative and incremental method, consequently a concept test were done employing a prototype that allows the validation of the suggested model.
