1.  Right now, we host and you can use usegalaxy.org ( main.g2.bx.psu.edu ), 
and test.bx.psu.edu.  Main will be the most reliable server and what we 
recommend you use, but test has a few beta tools that aren't available on main 
yet.  That said, test.g2.bx.psu.edu is very much for testing and breaking and 
shouldn't be used without acknowledging that.

2.  A local galaxy instance is hosted locally, on your server(s).  If you have 
a local compute cluster or even a single beefy server that you can access and 
use, this is free, but comes with the caveat that you actually run and 
administer your own servers, install required tools, etc.  A cloud galaxy 
instance is hosted on Amazon EC2, and comes with most tools and many common 
indices installed and preconfigured.  The downside to this is that it does cost 
money ( http://aws.amazon.com/ec2/pricing/ ) to run EC2 instances based on your 
needs.  There's a lot more I can point out if you're interested in running your 
own galaxy in the cloud, but I would tentatively suggest that you experiment 
with our main galaxy server at usegalaxy.org, and potentially migrate to a 
local and/or cloud solution as your analysis needs demand.
