The cloud computing framework of the hydro information system is based on three concepts that are
closely related: cloud, service oriented architecture and web geographic information system. The
architecture of the prototype hydro information system contains three tiers. The bottom tier is a
distributed relational database (PostgreSQL, PostGIS) that store geospatial and other types of data.
The middle tier is GeoServer web application that manages and presents geospatial maps and data
from the bottom tier. GeoServer is a platform that abstracts relational database and provide data
services for the developed web services using OGC (Open Geospatial Consortium) standards. The
top tier contains three developed web services: 1) web service for geospatial data management 2)
web service for supporting water resources modeling and 3) web service for optimization of water
resources. The web services are build using several programming languages (JavaScript, AJAX, PhP,
Java), additional applications (Eclipse, ESRI ArcGIS, Adobe Dreamweaver), libraries (OpenLayers)
and geospatial standards (OGC). All components and software packages of the hydro information
system are open source. The cloud framework for the hydro information system is flexible for adding
additional services and components. The system advantages over previous technologies are in
accessibility, availability, flexibility, distribution of computational resources, scalable computation
power, interoperability, internet based collaboration platform and dissemination of valuable information
over the internet, between stakeholders and general public.
