Copyright © 2019 the author(s). The concept of Information-as-a-Service (InfaaS) is a critical concept for disaster management applications. In the disaster management, the flow of data and the synchronization of information between different sites must be maintained to facilitate the decision making process. InfaaS-compliant application need to satisfy clarity, synchronization and continuity, the mechanism of distributed visualization system is suitable as the application platform for developing and deploying those applications. The distributed visualization system provides clarity and synchronization. Additionally, for achieving the continuity in the distributed visualization system, the Software-Defined IT Infrastructure has been studied and developed. However, a mechanism to autonomously control components of Software-Defined IT Infrastructure is currently lacking. In this paper, we propose a resource manager that handles the behavior of these components comprehensively. We extracted the required functions for the Software-Defined IT Infrastructure and designed an inner structure of the proposed resource manager to introduce required functions.
