Hey guys, I’m currently testing the stability/speed of using Amazon EC2 instances for a quick Cycles/BI render farm, using the Blender Network render. Testing OC is free 
For those who use the network render addon, the master node’s address is here: “ec2-54-224-34-42.compute-1.amazonaws.com”
To view the running jobs and slavfes, go here (in browser) “http://ec2-54-224-34-42.compute-1.amazonaws.com:8000/” Please don’t mess around with this 
Costs from Amazon are 7c/hour spot pricing on Quad Core machines, with some 16core/32thread machines going for 27c/hour at times
The master node is on a ordinary instance so it won’t get shut down if the costs rise too much.
Edit: Server is currently down, will edit when re-enabled.
