Re: Hosting a Large Number of Node Apps on the IBM i

Glad to have you enter the conversation, Niels!

Have you checked out the clustering built into Node.js?
https://nodejs.org/api/cluster.html#cluster_how_it_works

I have not delved into it (yet).  I don't know if this feature is available
in the IBM i version because Node.js just jumped from v0.12.x to v4.x.x
(still doesn't make sense to me :-| ).
