The most authoritative book on Google App Engine, this book explains how to build infinitely scalable web applications using this exciting new development platform and the the Java Runtime Environment (JRE). You'll not only learn how to perform common development tasks using App Engine APIs and services, but also what types of web applications are best suited for App Engine -- and what types are not. Programming Google App Engine introduces you to App Engine's tools, including the SDK and the Admin Console, with a simple application. You'll learn data modeling in the App Engine data store, as well as schema migration, queries, and transactions. With this book, you will also:

• Discover the difference between traditional web development and development with App Engine

• Learn details of App Engine's Python runtime environment

• Understand how the App Engine handles web requests

• Get techniques for effectively using App Engine's distributed datastore

• Manage deployed applications, performance, debugging, and unit testing

Anyone building large web applications, growing a small company, or looking for a way to build infrastructure will want to explore the nearly unlimited computing power Google provides. Written by Google's Dan Sanderson, Programming Google App Engine offers you clear and concise instruction right from the source. This book is still in progress, but you can get going on this technology through our Rough Cuts edition, which lets you read the manuscript as it evolves, either online or via PDF.
