This document summarizes a presentation about using the Appcelerator platform with Platform as a Service (PaaS) providers to build mobile apps. It discusses how PaaS can reduce development time by providing common features like data storage, authentication, push notifications, and social integration. The presentation provides examples of using the Cocoafish and Stackmob PaaS providers with Appcelerator and Titanium to build apps. It argues that the combination of Appcelerator and PaaS allows developers to focus on their core app rather than backend infrastructure.
