Product seems useful.
However, as someone who has launched multiple products with the aim of improving on something inside AWS (some successful, some not), I want to warn you about pursuing this type of AWS-centric business model.
I can tell you from experience that if you start to see traction, AWS will not hesitate to rip it off and incorporate it into their console. A quick Google search will show a rich history of treating their "partners" in this fashion.
Be careful, and good luck!
