Just wonder the cluster of node.js is for cpu multi-core or for multi-server?
For the multi-core in the same cpu or multi-cpu in a same server, their communication speed is enough high to pub-sub.
But when the servers locate different place, how to gurantee the communication speed?
I mean when using cluster for node.js, what is difference of the 4 cases:
1.multi-core
2.multi-cpu in same server
3.servers in same local network
4.servers locate different place(different local network)
your comment welcome
If you want node processes on different servers to collaborate, you'll have to manage it yourself.
