[99s-extend] Distributed model?

[Jeremy Ong]

Make all the machines identically and add an haproxy (or equivalent)
machine to load balance between all of them. Haproxy can handle many
many requests. Keep in mind that with tcp, the load balancer is just
accepting the socket but then the client communicates with the actual
application server directly afterwards.

I'm now looking at the best means of clustering this app.  I want to set this up so that, should the connection count get very high (which it will), then I should only have to throw more machines at this problem and it'll all go away.

I've heard hogging this line can be both a bottleneck and can potentially interrupt the heartbeat between nodes.  With this in mind, should I look at adding a ZMQ layer or some such to facilitate this?  What is the general solution to high traffic between nodes?
