Towards an Architecture for Electronic Notifications Services on the Cloud: A Model Driven Approach

Cloud computing technology is being adopted by organizations driven by their need to reduce operational costs, and to deliver scalable and flexible services. Solutions deployed on the cloud are a great point of interest in the commercial and governmental area for e-commerce transactions. Here, electronic invoicing applications play a key role in commercial activities, being a branch of vital importance for the business activities. In order to accomplish certain tasks (e.g., collection of overdue invoices, notifications about payment plans) technological solutions have been proposed. Then, it is important to establish architectures that support developers in creating notification solutions in order to send messages about issues of interest for organizations in a proper manner. Moreover, due to the constant changes of laws, a model driven approach can help as a flexible and maintainable option for these solutions. Therefore, this paper proposes an architecture for the creation of electronic notifications, which allows a good communication between organizations and their clients. In this context, a case study is presented in order to demonstrate the instantiation of the proposed architecture in a real scenario.
