摘要: This paper presents a practical case of study that analyzes the behavior of a distributed storage architecture, which was developed on a hybrid cloud computing environment. Open source software was used for implementing this architecture. An elastic service can be supported by virtualization technologies that allow the architecture to increment and decrement resources on demand. Performance and resource consumption were evaluated applying different replication techniques, which offer several levels of data availability and fault tolerance. The obtained results help to identify the benefits and limitations that arise when a system based on this architecture is implemented. The prototype allows us to visualize some trade-offs when applying different replication techniques depending on the availability, efficiency, fault tolerance and privacy required by users.
