Motivation
Network is the computer !
Web based GIS (Geographic
Information systems)
Water as Indispensable resource for our future

3. Cloud computing
3
Cloud is a system that enables
data processing, software and
access of data services
independently of physical location
and configuration.
Similar to this concept is the
electric grid where users utilize
power without understanding the
system components.
Pillars are: Cloud computing, Service Oriented Architecture (SOA) and Web
GIS
Research published in Journal of Computers and Geosciences “Development
of a web application for water resources based on open source software”

4. 4
SOA enables :
• Integration independent of
the programing language.
• Components reuse
• Improving the existing
systems
Functionality of system based on
SOA is in interoperable services
that work on different information
systems. SOA defines how to
integrate heterogeneous
application and platform into web
based solution.
Service oriented architecture

11. Web service for water resources optimization
(reservoir optimization)
11FOSS4G-Europe 2015 July 14th - 17th 2015, Como
Novel reservoir optimization algorithms (coded in Java)
• Nested Dynamic programming
• Nested Stochastic dynamic programming
• Nested Reinforcement learning
Multi-objective optimization algorithms

12. Discussion and conclusions
 Distribute web services between the two VMs and connect them
appropriately was successfully accomplished
 NIST definition of cloud computing
 On-demand self- service.
 Broad network access.
 Resources pooling, multiple front ends (OpenLayers), GeoServers
and PostGIS&PostgreSQLs
 Rapid elasticity (controlled by cloud environment)
 Measured service (user management service)

13. Discussion and conclusions
 Real time collaboration platform capabilities (tested with multiple
students)
 Open source software (OpenLayers, GeoSever,
PostgreSQL&PostGIS) & standards (OGC) and custom prototype
code (PHP, JavaScript, Java, Ajax,etc)
 Concerning service models - SaaS. The current deployment model is
hybrid of public - private cloud.
 The data is stored in the private cloud while services on public cloud.
 This is a specialized case of web GIS application.
 The architecture can be a foundation for complete cloud GIS
application similar to desktop application
 Others has already moved to the cloud Windows Office, Adobe
package (Photoshop etc.), ESRI ArcGIS, CartoDB etc.

14. (relatively) New technologies and possibilities
NoSQL technologies
Too many options and
varieties
MongoDB (GeoServer support)
http://boundlessgeo.com/2014/06/mapping-
worldcup-opengeo-suite-mongodb/
Hadoop, Hive etc.
Geospatial support missing
Cloud
Amazon Web Services
Google Cloud Platform
and many others
(hybrid clouds)
Facebook, Google, Microsoft (and others)
Increasingly open their projects (and source code)
PRESTO Distributed SQL Query Engine for Big Data
