description: The theme of the final qualification work: "Combining cloud storage"
This work outlines an approach to creating an application that will combine cloud and local storage systems.
Following tasks have been solved during the search:
1) To explore ways to integrate storage systems and disk devices.
2) To consider ways of mounting cloud storage in the file system.
3) To develop a server application for combining cloud storage systems.
General concepts and possible ways for combining data storage systems are given. The analysis of cloud storages, data storage systems and block storage devices (disks) is carried out, and existing solutions for mounting cloud storage systems in a file system and similar solutions, that allow to combine data storage systems are considered. A variant of an application implemented in the Java programming language by using Vert.x library (RxJava) and PostgreSQL DBMS is considered, an example of the architecture of such a program is described.
An application has been developed - a server for combining Yandex.Disk cloud storage and local storage, and the functionality of the developed solution has been tested. Possible options for the developed application are presented, as well as options for further improvement of the application are described.
