Distributed Systems Combined with Advanced Network: Evolution, Applications and Challenges

As an effective and popular method to solve big data storage, computation and processing, distributed system has been a widespread hot issue for these years. With the continuous development of modern computer, network and communication technology, distributed systems have also gained very huge development and have shown themselves some different forms in different times. Currently, there are some famous distributed system forms available for modern information processes and communication applications, such as web service, grid computing and cloud computing technology et al. In this paper, we mainly focus on studying the key issues of distributed system firstly, especially, for its beginning development phase, and then discuss the typical forms of the distributed system from its emergence, at the same time; we also show some important applications about up-to-date distributed system. Finally, we talk about the issues of challenges for up-to-date distributed system and the development trends of distributed system in the future.
