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

Correct. Many of the packages that are out on perzl.org
do work very well on PASE on IBM i. The PASE container really is an AIX
kernel that is imbedded into the IBM i OS. Well, technically side by side
with a great number of hooks that allow the 2 side to chat. Yes, I have
head of more then one person running the NGiNX on IBM i in this manner.
If you are doing some basic web serving it will be fine. The Apache
server has a number of advantages vs NGiNX (running in this manner) and
its all surrounding the integration to the IBM i OS. Being able to
understand the IBM i security, and file system, built in low level
Caching. But, when you look at using the right tool for the job, the
feature in NGiNX that you are after makes that an interesting choice when
paired with node.js.

I don't see any download for IBM I only for Linux and AIX?
