Inter-Instance communication via Hazelcast

[StefanSchubert]

Marvin has been prepared to use hazelcast to know each other, however container are usually isolated, and IPs hostnames are hardly predictable or controllable in a cluster environment.

It would be nice if we can improve this fact.

I would like to have hazelcast for beeing able to count the hits on a specific instance and to display the specific operation mode of a instance.
