The business benefits of Cloud computing to Cloud service providers, basically, come from the economy of scale. As a telecommunication operator who wants to become a major Cloud service provider successfully, the transformation of the current dedicated computing & network infrastructure into a commodity hardware-based Cloud computing infrastructures is necessary. In this position paper, we propose three technical consideration points for applying Cloud computing technologies into telecommunication operators' networks, i.e. Network Clouds. We think that guaranteeing time readiness, supporting service scalability and providing secure storage with cost-effectively are the most important things to be researched for realizing Network Clouds. Guaranteeing time readiness is necessary for running time sensitive network services on virtual machines. Supporting service scalability is required to run carrier-grade services safely and effectively using unreliable commodity computing machines, and providing secure storage to customers with cost-effectively is needed as a default service for introducing Cloud computing services into B2C and B2B areas. We present the results of experimentation to check the current state-of-the-art Cloud computing technologies for managing these consideration points. Finally, our on-going approach to transforming our telecommunication network equipments into a Network Cloud is described briefly.
