  3. 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. • http://cse651happ3.appspot.com/ CSE651, B. Ramamurthy

  4. 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 CSE651, B. Ramamurthy

  5. 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. CSE651, B. Ramamurthy

  6. 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. CSE651, B. Ramamurthy

  7. 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. CSE651, B. Ramamurthy

  8. 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.
