基于动态云的智慧农业架构研究-《计算机技术与发展》

文章信息/Info

摘要:: 云计算是所有数据汇集到云中心进行统一处理，用户不再需要部署计算能力很强的客户端，而是直接从“云冶里(服务器端)获得计算能力。流行的云计算架构采用强数据中心(服务端)、弱客户端模式。而建设云计算中心的强服务端，需要硬件高配置，需要良好的网络环境，造成建设云中心资金投入过大。对于智慧农业云架构，亦是如此。目前智慧农业的各网络客户端硬件配置优良。文中提出基于动态云的智慧农业架构，该架构通过将具有一定存储能力、数据处理能力、能够提供一定网络服务能力的客户端，根据需要，结合到云数据中心，使该中心的规模动态地扩大或者缩小。实际上，就是让某客户端为云服务中的其他客户端提供服务，减轻实际云数据中心的数据存储、数据处理、资源配置等压力。基于该动态云的智慧农业架构部分已经实现，并且在南京和安徽地区的部分农产品的各环节中得到稳定应用，证明了该架构的实用性。

Abstract:: The cloud computing is a model of collecting all the data to the cloud center to process centrally. Users no longer need to de-ploy a strong client,but obtain computing power from the "cloud" ( server) directly. So the cloud computing has a strong data center ( server) and weak clients mostly. The server requires high hardware configuration and high performance networks. That will require a large investment. It is the same to the wisdom agriculture. Now the clients which have storage capacity,data processing,and a network services,will be architected in the cloud. So the cloud will be expanded or contracted dynamically. In fact,a client will provide services for other clients to reduce data storage,data processing and other pressures of the actual cloud center. Part of the architecture of the wis-dom agriculture has been applied stably in Nanjing city and Anhui province. It proved that the architecture is practical.
