Startup Cloud 66 isn't exactly a platform as a service (PaaS), but it does some of the same things as a PaaS. It analyzes code stored in GitHub and determines what services would be necessary to deploy the application on Amazon Web Services, Digital Ocean, Joyent, Linode, Rackspace or Telefónica. It can then set up the necessary configuration for the user's choice of cloud computing service, greatly simplifying the cloud deployment process.
Cloud 66 also makes it easier to move an application from one cloud to another, and it includes some monitoring and management capabilities.
For now, Cloud 66 supports only Ruby on Rails applications. More information is available at Cloud66.com.
