Interesting article about cloud computing on Slashdot today:

Hi, all.
I am interested in learning what kind of experiences users of Amazon's EC2 resources have had. What resources have you used; what has been your experience with availability, ease of use, cost, data transfer, privacy, etc.?
TIA,
--Doug

Doug,
I don't have direct experience with EC2. However, I attended a computational biology conference about two years ago in which Amazon gave a talk on the system. Here's what I distilled:
1. If computation-to-communication ratio of your application is >> 1 (e.g., the SETI power-spectrum analysis problem), EC2's network performance is benign. If, in order to realize a time-to-solution in your lifetime, your application requires a computation/communication ratio approaching 1 (e.g., an extreme-scale adaptive Eulerian mesh radiation-hydrodynamics code), the EC2 network is your enemy.
2. For comparable problem setups, EC2 was less expensive than buying time on IBM's pay-per-use Blue Gene system.
3. For comparable problem setups and theoretical peaks, over the lifecycle the EC2 is less expensive per CPU-hour than a cluster of PCs linked by fast Ethernet.
4. There was general agreement among the half-dozen or so users of pay-per-use commercial clusters who were present at the talk that EC2 gave the best bang for the buck.
