Abstract:
The interfaces of the existing integration systems of digital watershed simulation models are not uniform. The integration is difficult between integration systems and models. The system lacks versatility and scalability. To solve the problems mentioned above, this paper built an open, scalable, and shareable integration architecture for digital watershed simulation models by using SOA and cloud computing technologies. In this architecture, the various transactions in the cloud service system were decomposed into services of different granularities, and the sub-functions were packaged as standard web services. Taking advantage of the typical modularity feature of SOA, the integrated architecture was divided into client layer, cloud service platform, cloud computing application interface layer, model management service layer, cloud service management layer, and physical resources layer. The application system services of the integrated model originated from these layers. This architecture enhanced the openness, interactivity and versatility of water conservancy model platforms.
