| Summary: | 碩士 === 國立政治大學 === 資訊管理研究所 === 100 === Drawing on the rapidly growing Internet technology, people now work and live in a more convenient way. Due to the progress of cloud computing, more and more companies as well as people are using cloud computing as a platform in order to backup and publish data.
There are three ways that how enterprises deploy cloud computing: public cloud, private cloud and hybrid cloud. In order to reduce costs, enterprises now days store their data using public cloud and entrust to the public cloud providers, such as using Google Docs, G-mail. Enterprises can also build private clouds to provide files and internal services backup. In addition, enterprises are able to combine public cloud and private cloud into hybrid cloud. We are used to store less sensitive data on the public cloud, while using private cloud or local storage to store highly sensitive data.
This study aims to design a system that can solve the problems regarding authentication, file content synchronization and authorization, while enterprises benefit by using hybrid cloud storage. System is designed by taking Google Docs as an example for the public cloud, Hadoop as the example for private cloud, and Linux-base computer as an example for local storage. This research addresses the open standard, namely: “OpenID” and “O’Auth”, in order to solve data content and non-consistency permission between public cloud, private cloud and local hosts.
