I have a question similar to this one.
I've taken a first foray into Ec2 - I expect really really low usage and have no power user requirements, and so I thought that the free instance would be ideal.
All I have done so far is bring up the instance, and
yum update it. I checked the billing estimator, and it already seems to think that that I am accruing charges. it's not much, but I still feel slightly like I'm being nickel and dime'd - wondered if anyone had any guidance on keeping a free instance really 'free'
