Evaluation of Resource Management System for InfaaS-adaptive Disaster Management Application Platform.

The concept of Information-as-a-Service (InfaaS) is important for collaboration-based disaster management applications. For satisfying this concept, collaboration-based disaster management applications is required to have three functionalities: clarity, synchronization, and continuity for information-providing. Since these functionalities are needed to handle not only application-layer but also infrastructure-layer, it is difficult to develop functionalities on each collaboration-based disaster management application. From this consideration, we aim to realize InfaaS-adaptive disaster management application platform which enables to provide three functionalities. Though the clarity and the synchronization are met by functions of distributed visualization system, the continuity requires the mechanism that can tolerate partial failures of IT infrastructure components caused by the disaster events. Thus, we have been studying and developing Software-Defined IT infrastructure which enables to manage various infrastructure resources by software. Though the previous study achieved the recovery of assigned resources on each IT infrastructure component, a mechanism to handle all components of IT infrastructure is required for autonomous recovery. Therefore, we propose new resource management system which enables to control all components of Software-Defined IT infrastructure comprehensively. In this paper, we introduce the architecture of proposed resource management system and evaluate the behavior, performance, and effectiveness.
