With the rapid development and the promotion of information technology,it is common that in the project construction,the reduplication,such as hardware,network,database,software platform and so on occurs in planning and construction. The more systems the project builds,the greater the challenges to the deployment and operation of operating systems and application services,resulting in a waste of hardware resources and higher maintenance costs. This paper introduces the use of cloud computing and big data technology to build a common service platform for seismic information in the earthquake information project. Through unified infrastructure construction and resource management,the platform provides a series of earthquake-related system of the common services so that users can carry out the development,deployment and operation with the efficient and flexible system based on the cloud platform,which greatly improves the efficiency in time and resource utilization.
