Amazon Web Services, the fascinating infrastructure behind many of the web applications you probably use every day, is about to come out from the shadows and meet end users directly. Amazon DevPay entered general availability today. The system handles billing and payment collection for software built on Amazon storage and processing systems, if the developers wish to use it.

In a world of online fraud and flaky customer service, the prospect of having Amazon handle payment collection for apps sounds great to us.
Amazon Web Services is actually bigger, bandwidth wise, than the rest of Amazon’s web properties all combined. The data arm is now branching out into making public data available for mashups, something we’ve been excited to see the UK Guardian do as well.
A number of companies have been beta testing Amazon DevPay, from cloud monitoring service Hyperic to photo sales app SmugMug.
DevPay charges 30 cents per transaction plus %3 of costs to customers beyond the cost of the Amazon Web Services charged to developers.
