Open Source Client libraries for Amazon Web Services are available to build AWS manager console.
http://code.google.com/p/typica – Java
http://code.google.com/p/ctypica/ – C
http://tarzan-aws.com/ – PHP
http://code.google.com/p/php-aws/ – PHP
Now comes AWS manager built using the above libraries:
DirecEC2 for iPhones and iPod touch
What about setting up a Cloud42 application on a webserver and offer the services same with Ylastic?
Amazon EC2 Management console for users who will win?
What if to include the feature to easily manage 1000 servers using iPhone?
Ylastic offers application for iPhone and iPhone and Android based smartphones. But I bet they built their own client library for their application.
