[support] CPU usage

[Daniel Carrera]

Hello all.

First of all, I'd like to thank everyone or their help so far.

My website is likely to be very low traffic most of the time, but with a 
few sharp spikes. Most of the year it's quiet, but close to the end of 
the school year it gets much busier. Most of the day it is quiet, but 
when one classroom starts using the site, I have 30 new users.

Is this site a good candidate for cloud computing, such as Amazon's EC2 
service? My very limited understanding of EC2 is that it is "pay per 
use", so when the site is quiet we pay little and when there's a spike 
the service expands and we pay more. Is that correct?

Is that how cloud computing works? Do you think that the cost of EC2 for 
us might be somewhere in between a shared host and a dedicated host? I 
was thinking that EC2 or similar might be a way for us to bridge the gap 
between a shared host and a dedicated host. But I'm not sure.

Thanks again.

Daniel.
