No, I have a single cluster, each micro-service is an Akka system that is subscribed to cluster events and once a system is up, it sends a message to every other node saying, hey, I'm here, lets exchange information, call it, synchronizing their cache.
Risky?, Akka follow the let-it-crash philosophy which has been proven to be very safe in Erlang in the Telecom industry and Akka cluster uses gossip protocol so I'm relaying on an existing functionality to keep my systems updated. If you are not going to send messages (remotely) between systems then why use Akka at all? It is like, oh, I like Akka but I don't want to use its messaging system. That being the case then people should be afraid of CAP theorems, CRDTs, eventual consistent data and just use the good old messaging systems like RabbitMQ and relational DBs, etc, but then, they are not that safe anyway. I have my system running on a controlled environment and in production now for almost a month and I haven't lost a message, the bugs I have fixed have been related with my own code. Network failures are going to happen and in that case any system can fail so risk is only a relative word.
