Amazon Ec2 For Cs-Cart?a

Would appreciate any insights from those who are using, have used or have looked into Amazon EC2 to host a CS-Cart website. Is it cost effective and free of compatibility issues? How is performance? I noticed their support forum had no responses to several questions I was interested in. Is their free basic support adequate? What ACI are you running?

EC2 is attractive to us only if it essentially insulates me from any service-specific technical issues; that is, if it can be thought of as just another generic linux web server once configured to run CS-Cart.

Thanks in advance for any shared experience.

Its free up to a point per month then you have to start paying once you hit a certain traffic limit.
