The wizard to create Amazon EC2 instances from within the Orion console is ABSOLUTELY AWESOME!!! But, it is missing the Micro insance option. The Micro instance is free for one year and only $0.03/hr after that! It is designed for servers with short bursts of CPU utilization. Sounds like a perfect use case for SEUM. I changed my Orion EC2 instance from Small to Micro and have been running like that for almost a month and can't tell a difference, other than I am not paying Amazon anymore! I think Micro should be an option in the wizard for people with a small number of transactions (probably less than 5).
