The pay-as-you-go won't be enabled until sometime around the end of the year.<p>The quoted CPU pricing "$0.10 - $0.12 per CPU core-hour" is similar to Amazon EC2 small instance pricing ($0.10/hr), but it's probably not a straight comparison. AppEngine seems to charge by the sip, as might be expected from a compute utility, while web apps will probably require a minimum of 24x7 usage of an EC2 instance. So AppEngine should be less costly on the low-end.<p>Here's an interview with some AppEngine managers on the announcements tomorrow:<p><a href="http://readwritetalk.com/2008/05/27/pete-koomen-paul-mcdonald-product-managers-google-app-engine/" rel="nofollow">http://readwritetalk.com/2008/05/27/pete-koomen-paul-mcdonal...</a>
yawn.... ok. I can't think of serious startups using their services. Maybe if I am doing something quick, a small app, while having a full time job. etc...<p>At least with amazon, you have controll of the servers, and can install whatever you want. With Goggle App Engine your are tied to it to the hip.<p>And Google has been getting eviler lately. For some reason I wouldn't trust my source code with them, while I would trust amazon a little bit more.
<i>The big announcement will be around Google App Engine - expect the 160,000 or so developers on the waiting list to be let in tomorrow (75,000 have been given access already).</i><p>That's a lot of entrants to the web 2.0 market.
