I’m considering moving my blog to either MS Azure or Google App Engine, using either an ASP.NET or Python blogging engine, but I can’t understand how they will charge me for CPU usage. The bandwidth and storage charges seem straightforward, but not the CPU...

According to the services' respective documentation, I will pay either $0.12 or $0.10 for an hour of CPU usage. Does that mean I will be charged approximately 30 days * 24h * $0.12 = $86.40 monthly regardless of the number of visitors and the complexity of my code? Will I pay the same CPU price when I have 2 visitors a day as when I have one thousand?

Google App Engine charges for actual CPU time, as implied by their partial unit FAQ answer:

No it depends on the number of CPU hours you actually use. If one visitor's request requires 1 second of calculation, 1 visitor per day will cost you $.12/3600 daily, 3600 visitors/day costs $.12/day, etc.

No, When someone charges you on CPU - it for actuall use of the cpu by a process that serves your app.
