Been trying out the AWS admin console from Ylastic (it also works with Eucalyptus and Sun Cloud Services) as well as their iPhone app. I have to say I am pretty impressed so far. It goes well beyond AWS in terms of features and includes RDS, S3 and EBS support built it. It’s still lacking a few niceties which I am talking to them about but it’s really pretty strong.

At $25 a month it’s a little expensive for the individual but cheap for a company. They have a one week trial period.
