Abstract(in English) The recent trend of the cloud indicates that computational-resource consolidation with the virtualization technique is effective to reduce the TOG (Total Cost of Ownership). The consolidation has also good effect to keep the system reliability high by reducing the distribution of low reliable components. However, if some failures occur in a cloud center, a sphere of their effects on service tends to become larger by the consolidation. Moreover, there is the possibility of leaking important secret data, those are never disclosed if they are stored in their local systems. Thus, it is important to grasp the relationship between its cost and dependability of a cloud. In other words, we need to construct a cloud center with considering both the initial cost for dependability and running cost including power consumption of the system. Since these issues related to the cloud are truly the specialty of researchers on dependable computing, their high activities are desired. In this paper, we overview the recent topics related to the cost and dependability of the cloud, and show an approach to reduce energy consumption of a cloud system with keeping its dependability.
