OpenShift from RedHat

I don't know if you are aware of OpenShift from RedHat - but if you don't try it. It is really good place for trying technologies or developing new projects. For free you get three slots for applications that you can use various technologies such as:

• JBoss Application Server 7 or JBoss Enterprise Application Platform 6
• Tomcat 6/7
• PHP with Zend Server
• AeroGear Push 0.X
• CapeDwarf or WildFly 8
• Drupal 7 or WordPress 3.X
• Node.js
• Ruby or Python, Perl or even Google Go
• MongoDB, PostgreSQL or MySQL
• and others...

As you can see it offers really lot and for free - I don't know better service for freelance developers.
