分析了云计算在地震灾害管理中应用的国内外研究现状；阐述了云计算技术的基本内容和分类，根据地震灾害管理主体涉及到的信息交互情况，构建了地震信息共享平台功能模型，明确了地震应急状态下信息共享流程；提出了云计算地震信息共享平台的体系结构，包括云计算服务方式和云计算服务层次两种，并探讨各体系结构的优缺点；最后分析地震灾害管理部门对可信云服务供应商进行选择时考虑的因素，即云服务认证情况，为相关部门选择供应商提供借鉴。%In this paper, the current research of cloud computing applications in earthquake disaster management is analyzed. The basic content and classification of cloud computing are described; the functional model of earthquake information sharing platform is built according to the information interactions of earthquake disaster management subjects, and the earthquake information sharing process in emergency state is cleared. Then a cloud computing architecture of earthquake information sharing platforms is set up, including architecture in accordance with cloud computing service modes and services levels, and the advantages and disadvantages of the two kinds of architectures are explored; finally, factor of how to choose trusted clouds service providers by earthquake disaster management department are analyzed, that is cloud services certification status, which providing reference to the relevant departments for cloud computing suppliers selecting.
