Hi Amos, Etzion,

You are talking about 15 seconds for bringing up the machine, and about
shutting down the machine according to idleness detection. Last time I
checked (and maybe I am not up-to-date),
1. It took about two minutes to bring up the machine.
2. Amazon charged per full hour. That is, if you use the instance for 20
minutes, shut it down and then bring it up for 20 minutes, you pay for two
hours. So it might be beneficial to wait a bit, at least until the end of a
full hour.
