I search for Database System/Application, that I can make a Cloud Computing Database Service such as Amazone SimpleDB, Google BigTables or Microsoft Azure SQL. It would be best, if it were opensource and if you can use it on GNU/Linux or anthor opensource os, but both not compellingly.

I already looked for some time in the Web, but I found nothing. I hope for the support community and I will also further-look for and everything which I find posts.

I am grateful for each reference

This is private idee and I hope for your support, thanks

And sorry for my english

Update:

I find somethings http://www.mysql.com/products/enterprise/cloud.html but that's not that what I want..
