Very buggy
I found this instance to be very buggy and Magento was almost unusable due to the the repeated errors that something went wrong and several others. I spent almost a day on this, including resetting the instance once and finally gave up. I chose a different AMI with Magento, and having the fortunate opportunity to compare this side by side with a working release, I can be confident in my assessment that this is a very poorly released image, I do not recommend it. You'll spend a tremendous amount of time trying to fix what should work out of the box. This was not ready for release, and I would caution to stay away from this vendor based on this experience.
