The paper describes the development of information technologies for distributed storage of data of instrumental observation networks created by the Far Eastern Branch of the Russian Academy of Sciences (FEB RAS). The prime goal of the distributed storage design is to process a large amount of real-time seismological data and provide fast and secure access using a cloud storage platform based on OpenStack Swift. On its basis, the allocation of the corresponding data storage has been done. The interaction with storage using existing application software as well as an assessment of the effectiveness of the solution is described.
