This may be a game-changer.

This new service allows entrepreneurial developers to wrap their own business models around Amazon S3 and Amazon EC2, taking advantage of Amazon’s existing customer base and billing infrastructure. With DevPay, developers can focus on being creative and innovative while dispatching the less-than-glamorous aspects of dealing with bank accounts, credit cards, and so forth to us.

As someone that has built more web applications than I care to remember, I am still amazed at how many elements of the web business are built over and over again.

They now have the complete package for some types of startup projects. Letting developers focus on the user-side of their service, instead of recreating the wheel.

Brilliant next step by Amazon.
