数字资源长期保存混合云平台技术分析

Analysis of Long-term Preservation Hybrid Cloud Platform of Digital Resource

传统的数字资源长期保存方式面临着来自容量需求、便捷利用、有效组织管理等诸多方面的挑战,而云技术可以其存储容量大、计算资源丰富、灵活易扩展、共享方便、成本低廉等优势有效弥补传统数字资源长期保存的不足。在详细分析长期保存云平台现状的基础上,对长期保存云模式的选择进行了深入探讨,并依此提出依托混合云技术构建长期保存云平台,进而对数字资源长期保存云平台数字对象模型进行了详细的设计和论述。

Traditional long-term preservation faces more and more challenges, such as storage capacity, convenient utility, efficient management. While cloud technology has many advantages such as large storage capacity, abundant computing resources, flexible and extensible, easy share and low cost etc, which can cover the shortage effectively. Based on analysis of the current status of long- term preservation cloud platforms, this paper explores deeply different cloud models, puts forward the construction of long-term preservation platform depending on hybridcloud technology. Further, it designs the digital resource long-term preservation hybrid- cloud platform model, and the digital object model accordingly.
