title: Cloud virtual machines available for free for open source testing?
body: <p>Anyone know about places in the cloud where you can create (virtual) machines (like Amazon EC2) to use for your computing tasks - places that offer a number (at least 5-10) of free machines, if they are used for testing open source projects?</p>
  
  <p>Im not looking for places hosting CI environments like Jenkins, Hudson, TeamCity etc. for free for open source projects. Im looking for a place where I can run some servers where I can setup the open source system itself in a clustered and distributed environment. Then drive a test against that clustered and distributed environment from an automated test (e.g. executed from a CI environment).</p>
