Number of cloud platform (PaaS) offerings is increasing every day and it became quite a challenge to keep them all in mind, so I started an open for editing spreadsheet that is updated by the cloud enthusiasts every day. As of March 2012 it contains a list of 54 platforms with following information:
Name, Description, Language(s) supported, Frameworks Supported, Website, Development Status, Twitter, Vendor Name, Number of Developers, Number of available applications, Maturity (in years), Billing Model, Performance, Number of outages, Who is using it, User Rating (1-10), Comments.
The document also contains a second worksheet with mobile platforms.
If you find that some platform is missing, feel free to add your bit at
