110 hours of rendering time on the “High-CPU” machines at Amazon EC2 cost me $55. The storage and transfer fees were negligible.
High-CPU machines are 8-core with 7 gigs of RAM… so, as the cloud render farms calculate it, I had 880 core/hours.
One of the cloud renderfarm services charges $.70 per core hour. 110 hours * 8 cores = 880 core/hours. 880 core/hours of time on their service would have cost $616.
I’d say Amazon EC2 is one hell of a bargain if you have the technical know-how to do it yourself!
