A Study on Distributed File Systems: An Example of Nfs, Ceph, Hadoop

Distributed File Systems (DFS), are systems used in both local network and wide area networks by using discs, storage areas and sources together. Nowadays, DFS makes possible operating big data, large-scale computings and transactions. The classifications are performed based on their working logics and architectures. These classifications were performed based on fault tolerance, replications, naming, synchronization and purpose of design. In this study, firstly the examinations on general design of DFSs were performed. Later, the results were discussed based on the advantages and disadvantages of Ceph and Hadoop and Network File Systems(NFS), commonly used in these days. Keywords- Distributed file system, Network file system (NFS), Hadoop, Ceph, fault tolerance, synchronization, replication, naming, operating system.
