App Engine FAQ's

Conclusion & Review

Q: What cloud service level does Google App Engine sit?

A: App Engine is a platform (PaaS) service.

Q: What do you need in order to get started playing with Google App Engine?

A: You need to get the SDK from Google. Use this downloads link to get the one for your platform. The SDK comes with client libraries which you'll use to connect to the various App Engine APIs, a set of command-line tools for administration, and a development server. Mac and PC users also get a bonus: a GUI called the "Launcher" that gives a friendly interface to users and provides access to a subset of the command-line tool functionality.

Q: How do you create your first App Engine application?

A: Either use the Launcher to create a new application which generates boilerplate code, or create it by-hand.

Q: What is the development server and how do you start it?

A: The development server gives users a way to test their application during development. It runs locally allowing users to execute their app without being required to upload it to Google. You can start the development server either by pressing the "Run" button in the Launcher or use the dev_appserver.py command-line tool.

Q: How do you upload your application to Google?

A: Similar to the previous question, you can either click the "Deploy" button in the Launcher or use the appcfg.py command-line tool.

    def get(self):
        self.response.write('Hello world!')

  The "Hello World" app files are next
  look at the most important of these files: app.yaml and main.py
  these are automatically generated by the Launcher if using that tool. 
  If you’re on a system without a Launcher, you’ll need to create these files yourself.
