Amazon AWS announced Spot Instances of EC2 a few weeks back. I have been very interested in this concept. Auction pricing should be natural for the cloud computing utility model. They will be selling spare capacity from moment to moment. The cloud is attractive since servers often site idle. Sharing that resource makes sense. “Spots” are an extension of the concept to keep AWS at full utilization. Win for AWS and customers. I look forward to seeing how this play out during 2010!
