Abstract

Cloud computing is a challenging and promising paradigm shift in the IT world. Examples of cloud services like Google Apps and Microsoft Azure represent a new paradigm for the provisioning of computer infrastructure, diminishing the costs for creating and maintaining software and hardware for users with infrastructural needs. Next Generation Networks (NGN) decouple services from the transport plane in order to provide flexibility with a common control architecture. This NGN approach offers faster integration of subsequent applications with the advantage of reusing the current deployed infrastructure. The integration of Cloud technology with Telecommunication infrastructures provides new revenue streams for Telecom operators through their converged fixed, mobile and data services and by offering "cloud computing data" services with NGN infrastructure features. This paper analyses interconnection scenarios for combining Cloud-based systems and an Evolved Packet Core (EPC) to offer new value-added applications in a unified architecture. The EPC and IP Multimedia Subsystem (IMS) are described as possible vehicles for the integration.
