With the increasing popularity of public Cloud solutions, the common tendency is to create new applications or to move the existing ones into this environment. Distributed systems are part of the change as well. This paradigm is very useful when the computation and storage resources of the machines does not represent a problem. Due to the variety of solutions offered by the greatest Cloud providers, these are no longer a barrier, as long as the client pays for the time consumed using the resources. On the other hand, there is a new category of devices, connected to the Internet, that surrounds people in everyday life. These devices do not have the same amount of resources as the Public Cloud, but working together, they can offer services that are faster and closer to the user than the Public Cloud ones. This network and the services provided by them represent the Edge Cloud. This paper propose a distributed and decentralized storage service running on edge devices, in order to optimize resource usage. This can be achieved by using their computation and storage resources which leads to a lower amount of money spent with public Cloud solutions that satisfy the same requirements.
