Abstract: As one of the important featured agricultural production bases in China, the most prominent problem that Fujian Province faced was the poor sale for agricultural products. Therefore, it was of great significance and role to construct the O2O cloud service platform for the featured agricultural products in Fujian based on the cloud computing technology and SOA technology. The advantages and key technologies of cloud computing were introduced in this paper, and then the difference between the cloud computing and cloud services was described. By using the SOA technology, a loosely coupled system structure was designed to reorganize the current resources. to implement the service model, and by using the specific Web Services technology and cloud computing technology, the main functions of the cloud service platform and the SOA architecture were designed, thus to construct the O2O cloud platform for the featured agricultural products in Fujian Province. Using the cloud computing to construct a cloud service platform for the featured agricultural products in Fujian could greatly save the costs of construction and maintenance, reduce the logistics costs and the agricultural product costs.
