Does anybody have any experiences with Amazon EC2 (

http://www.amazon.com/b/ref=sc_fe_c_...A36L942TSJ2AJA )? This could be a replacement for our HA setups, but I haven't used it so far, and the pricing is quite confusing. If you have lots of traffic, you probably pay a few hundred dollars per month...
