Figure 1. Cloud computing service layers. Study on Service-Oriented Cloud Conferencing

Abstract—Cloud computing, a new thing which is only three years old, becomes the most fashionable technology and developing trend in IT industry now. People say “X as a service ” in the cloud computing, which means that everything including software and hardware can be taken as a service for consumers in the cloud. Meanwhile, a high quality multimedia conferencing has been an urgent requirement these years. The products in the market are immature. They can’t support very large number of participants and multiple HD video in a meeting. In this paper, we consider conference as a service, and propose a feasible framework of multimedia conferencing in cloud. As it follows the structure of SOA, we name it Service-Oriented Cloud Conferencing. We then present the software structure and flow procedures. We prove that the cloud conferencing overcomes the deficiencies of existing products with the support of excellent characteristics of cloud.
