> According to the new architecture of Stratos, internal components communicate with each other via a AMQP based message broker using topics. These messages are sent in JSON format and each message is considered as an Event. 
> There should be an Event Publisher and Event Subscriber implementation which could be extended for different topics and each topic could define a set of events which illustrates its life-cycle.
> Topics:
> 1. Topology 
> Publisher: Cloud Controller
> Subscribers: Load Balancers, Auto-Scaler, Stratos Manager
> 2. Instance Status
> Publisher: Cartridge Agent
> Subscribers: Cloud Controller
> This implementation could be extracted out as a standalone component and shared among different components as the foundation for messaging.
