The portal front-end is written in PHP using the Symfony framework and runs on top of an Apache Web Server. 

In order to display the cacti graphs within the application, it uses a JAVA based web service called dispatcher running on an Apache Tomcat Server. This has three JAVA servlets: CactiGraphs (net.geant.eumetsat.CactiGraphs), JsonData (net.geant.eumetsat.JsonData) and TrendAnalysis (net.geant.eumetsat.TrendAnalysis)
