[ic] Request for comments and documentation - multiple server architecture

Hello all -

With regards to load-sharing strategies for high-traffic sites running 
Interchange: I have scanned the current docs, and searched the mail 
archives with terms like "multiple server", "load sharing", etc.  There is 
a smattering of info on this subject, but given the history and maturity of 
Interchange, I think more information on the topic is justified, so I am 
herein submitting a request for the development of some formal 
documentation on multiple-server architectures for Interchange.

This may not be the prescribed forum for a documentation request...but I 
could not find a specific directive for that at akopia.com, so here we 
are.  Also, I would hope that anyone on this list who has successfully set 
up an efficient dual- or multi-server Minivend or Interchange system would 
be willing to share some specific technical how-to's.

One approach I did find in the archives is to run Interchange and the http 
server on one machine, and the database server on the second - this seems 
relatively straight forward, and I would guess that the performance gains 
could be significant on data- and search-intensive sites.  One idea I had, 
in the case of graphic-intensive sites, would be to establish a separate 
image server, geographically separated from the Interchange/web-server, to 
relieve bandwidth bottlenecks.  Yes, images would come from a separate 
IP/Domain than the rest of the site, and this could be an issue with SSL - 
though just those images for the SSL areas could be accessed local to the 
same domain.

I encourage other listees, and Akopia, to respond to this thread.  My 
interest is not just academic; I have a client who is facing the prospect 
of a multi-server scenario very soon, if they continue growing at their 
present rate.  Let's push the envelope!
