Hi Cagri,

Never implemented one personally but checkout out Chapter 4 in the zguide, 
specifically the Majordomo and Binary Star patterns.


There's an implementation of the Majordomo pattern too if you want to check out 
what it would look like fleshed out. No redundant broker in the implementation 
though.

Subject: [**EXTERNAL**] [zeromq-dev] Load Balancer with Multiple Brokers for 
Redundancy

Hello,

I am designing and implementing a cloud system for a data streaming 
application. The machines are Ubuntu 14.04, clients are Java applications, 
workers are C++ applications. Both clients and workers will be in the cloud. I 
have read the Load Balancer in ZMQ Guide and it is almost exactly what I need. 
What I need is that there should be no single point of failures in the system. 
However, in the given design, if the Load Balancer goes down for some reason, 
the whole system goes down. Is there a known pattern for adding redundancy for 
the broker in the middle? Have you ever implemented such a system with ZMQ?
