A method includes providing a cloud-side database storing data, an objects model of the data, and a user interface (UI) model of the data. The method further involves providing an instance of an application server coded in JavaScript, for example, in a Node.js cross-platform runtime environment. The instance of the application server coded in JavaScript includes the logic of an application coded to process the data. The application logic is executed (and data processed) on either the client-side or on the cloud-side. The execution of the application logic (and processing of the data) is dynamically switchable between the client-side and the cloud-side.
