Twitter's robust REST API enables building of good applications that leverage its increasingly large and real-time data.

Google's cloud system App Engine not only provides a scalable platform for deploying applications, but also proves to be economically viable because of its pay per resource usage model and a large free quota.

Little wonder then, there are increasingly large number of twitter apps being deployed on App Engine.

In this post, I am going to examine how to create a simple application based on twitter's REST API and deploy it on Google App Engine. A deployed version can ...

I wrote a new tutorial on building a search engine using Appengine, and Yahoo Search API here. This uses pure Appengine API, and not Django, and is a tutorial on how to use Appengine without Django.

Google launched their EC2 competitor, Appengine yesterday, and all hell broke loose. And in about 24 hours, the 10,000 accounts were used up. Currently it is tied to only working with python, and Django 0.96.1 works out of the box. <!- - more - ->

The Good

• Python powered. Django works out of the box.
• No sysadmining chores.
• Promise of infinite scalability with no configuration. (Ah!)
• Free for now.

The Bad

• Python powered, if you want to use ruby/java/php, sorry you are out of luck.
• Your code is tied to Google. You might be able to reuse most of ...
