Summary: | 碩士 === 國立交通大學 === 管理學院資訊管理學程 === 100 === Business data is the most important asset of an enterprise. Many enterprises suffered great damage due to data loss caused by various natural disasters in recent years. People start thinking about the issue of data security and backup solution. With the era of the Big data coming and the rise of the cloud concept, a new storage model is proposed. Distributed systems, high performance and high fault tolerance features provide a good choice for data storage. This study implements a cloud storage with high reliability, high availability, high scalability, scale-out architecture, and virtualization. The entire system has a high degree of fault tolerance. No matter which one server room of a region failed due to natural disasters or any reason, resulting in regional failure. The entire system is able to rely on the normal operation of the other two regions and continue to provide services for a cloud storage service. This is very important factor for a cloud storage service. However, the performance will be limited by network, whether LAN equipment or WAN route planning is the key factor to determine the system performance. The system in this study can provide a private cloud for a small-scale enterprises. The network environment must be improved if it used in public cloud or large-scale environment. This study also implements some common cloud storage services such as WebDAV, Web-Base file manager and virtualization to verify the flexibility of this system.
