Implementation of a Collaborative Document Processing in the Cloud

Document processing is among one of the most widely used and well developed applications. With the recent fast development of high-speed internet and distributed computing, it becomes feasible to move document processing to web- and even cloud-based environment. The initial benefits of moving office documents into cloud for small and medium sized business are cost saving for purchasing, maintaining, and upgrading both software and hardware. However, the most significant advantage of this trend is to enable users of real-time collaborative editing on a shared cloud-based document. Therefore, moving office applications into cloud is an inevitable trend for the development of office application. A novel efficient document-processing model (DPC) in the cloud was proposed by the author in [12]. In this paper we implemented the DPC model in the Google cloud through the Google App Engine. Our preliminary cases testing results verified the proposed DPC model enabling users to process office document collaboratively with a proper granularity in the cloud.
