Animation
Description
initializations:
Once ESB and EasierGOV are conntected (see How-to connect EasierGOV to EasyESB) and Web Services of providers binded to the infrastructure of services, EasierGov is able to detect the Event Producers among the Web Services.
Thus, EasierGOV create correspondence table between topics and Event producers.
subscriber mode:
When a Event consumer want to subscribe on a specific topic, it send its subscription to PEM. The PEM invokes EasierGOV to known all Event producer able to provide the required topic and send subscriptions to all providers found.
dynamicity:
When a new Event producer is added to infrastructure of services and if this producer sends events corresponding to a topic required by a client, the PEM automatically subscribes the client to this new Event producer.
When a Event consumer want to subscribe on a specific topic, it send its subscription to PEM. The PEM invokes EasierGOV to known all Event producer able to provide the required topic and send subscriptions to all providers found.
