I am building an IM which can potentially support more than 100M users, Openfire cluster is one of my options. My questions are:
-
Can Openfire cluster support 100M register users? which probably means 10M concurrent users talking to each other at the same time for the cluster. I have many machines in the data center, just want to double check if Openfire itself can scale out that much with additional machine resources.
-
Will the openfire servers be in the same domain in the cluster?
Thanks,
Peter
