Cloud hydro information system and web services

Cloud computing, service oriented architecture and web geographic information systems are the main ideas for developing the cloud hydro information system and the web services. The cloud hydro information system is composed of relational database, middle tier for managing geospatial data, two web interfaces for the specialized services and other software components. Three main web services are developed in the system: (1) web service for managing, presenting and storing of geospatial data, (2) web service for supporting water resources modeling and (3) web service for optimization of water resources allocation. All web services are developed as prototypes and tested for their technical functionalities. The presented cloud hydro information system is a flexible platform for developing new services or upgrading the existing ones. The data, models and services are in the cloud and only a web browser is needed to use the system. Advantages over previous technologies and software solutions are in the availability, accessibility, scalable computation power, interoperability, distributed system components and the provision of internet-based collaboration platform.
