The recent emergence of Cloud Computing in the IT world has opened doors for new revenue streams and business models. The movement towards a service-oriented architecture and an all-IP based communication system has led to the IP Multimedia Subsystem (IMS) being accepted as the Next Generation Networks (NGN) service control-provisioning platform. The Telco 2.0 domain can benefit from service enhancement and Web 2.0 technologies such as Cloud Computing. This can be achieved by opening gateways and APIs guarding rich underlying network resources (e.g. location) to 3rd Party ASPs, thus adopting the delivery of Network as a Service (NaaS). Telco services are faced with opportunities to make use of powerful computational power and storage services offered by cloud environments to accelerate business-processing speeds.
