in thread CPU cycles DO NOT MATTER!

I factored that into my TCO. The actual cost for a decent server nowadays is about $4000. The other $6000 is the money spent on that server over 2 years. I'm assuming a sysadmin at $100k/year maintaining 50 servers, so that adds $4000. The other $2000 is power, rackspace, and other incidentals. That comes out to, roughly, $85/month which is rather high. I'm also assuming all free software (Linux, Apache, Pg/MySQL, etc).

Does that work out better?

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

    Seems reasonably fair. But to compare:

    On this (hypothetical - but close enough to the truth) project we've got about $100,000 in hardware and about $20,000 a year in hosting. This is one fairly large rack of machines. Assuming we'd have to double the amount of raw CPU power, that would probably go add at least another $40,000 hardware and something like $10,000 - $20,000 / year in hosting costs depending on how large the racks are. One man/month would cost roughly $15,000, probably a bit less. You can see there's some room here. :-)
