Per CEP: The Fiware CEP GE is the Proton (Proactive Technology Online) asset by IBM. It runs as a web application, on a platform such as Tomcat. The hardware requirements for the platform to would be at least 8GB Ram. Clients post events to this service and complex situations it detects are emitted according to the rules coded into it using a web interface. No programming skills are needed, yet clients need to implement RESTful calls with Json, XML or free text payloads to represent the events. When intensive stream of events needs to be handled, you can use a variation of Proton which is integrated with STORM.
