What is google app
engine?
• Google App Engine is a Platform as a Service (PaaS)
• It lets you build and run applications on Google’s
infrastructure.
• App Engine applications are easy to build, easy to maintain,
and easy to scale as your traffic and data storage needs
change.
• With App Engine, there are no servers for you to maintain.
• You simply upload your application and it’s ready to go.
• We will do that as a lab work today. We will deploy the
hangman application on the google cloud or google app
engine.
• Before we do that I want you to access and try the one I have
already deployed.

Lets see what happens?
• I am on the admin console. I am going to monitor
the traffic…
• The application that we developed has been
deployed without any change in code
• It supports applications developed in most
programming languages

GAE Features
• App Engine makes it easy to build and deploy an application
that runs reliably even under heavy load and with large
amounts of data. It includes the following features:
Persistent storage with queries, sorting, and transactions.
Automatic scaling and load balancing.
Asynchronous task queues for performing work outside the
scope of a request.
•
Scheduled tasks for triggering events at specified times or
regular intervals.
•
Integration with other Google cloud services and APIs.
•
•
•
• Applications run in a secure, sandboxed environment,
allowing App Engine to distribute requests across multiple
servers, and scaling servers to meet traffic demands.

How to deploy an
application?
• We will work from the Eclipse environment we have
already downloaded
• You need to download the Google app engine
plugin and use that to deploy the application.
• You need a google app engine account before
you can deploy anything. Please do that before we
proceed.
• On to the handout on google app engine handout.

GAE capacities
• All applications can use up to 1 GB of storage and
enough CPU and bandwidth to support an efficient app
serving around 5 million page views a month, absolutely
free.
• Runs your web applications on Google's infrastructure.
• Google App Engine is fully-integrated development
environment
• You can serve your applications with your own domain
(such as http://cse651.com), or you can use the App
Engine domain for free (just like
http://popworld.appspot.com)
• You can use server side languages such as PHP, Java,
Python, and Go.

Summary
• Among the cloud offerings Google App Engine has
the least expensive model for cloud deployment
• The learning curve for the process of deployment is
also not that steep.
• Moreover Eclipse has a plugin to simplify the
process.
• But all the infrastructure is hidden from you;
• You access them only through the API and the
services offered by the GAE.
