Great advice. I am hoping to roll out my own service offering (<a href="http://www.knowledgebooks.com/" rel="nofollow">http://www.knowledgebooks.com/</a>) in about a month, and I have been thinking a lot of how to keep hosting costs minimized and put in place sufficient automation that not a lot of my time will need to be spent, except for improving the service itself. This service is something that I need for two projects and hopefully other developers will find it useful also.
