We're here at the AT&T Developers keynote and CTO John Donovan just revealed that the network is building AT&T Cloud Architect. It's a developer-centric cloud that will help devs build cloud apps. There's a full API coming soon with a flexible pricing structure: you can pay monthly or hourly depending on your needs. It's also joining the OpenStack architecture, which Ma Bell's gonna rely upon to support the platform -- reportedly the first US telecom provider to do so. The company's planning to optimize APIs to the extent that 10 billion API calls will be made before the end of 2012.
