How to: Publish a Cloud Business App to Office 365 [paved over]
You can publish a cloud business app as an auto-hosted SharePoint app, which will automatically provision space in Office 365 for both the app and an intrinsic database. Specifically, the app will be hosted in Windows Azure and the database in SQL Azure. After you publish your app, others can start it from SharePoint on their computers and mobile devices.
You can also publish a cloud business app to SharePoint 2013. See Publish apps for SharePoint.
