Amazon EC2

Using Amazon EC2 to run large data analyses cheaply

Spot instances on Amazon Elastic Compute Cloud (EC2) allow researchers to do high performance computing at very low cost. For example, a 64-core workstation with 256 GB of memory can be rented at about $0.7 per hour, which is ~80% off regular on-demand prices. You can request 10 of such servers and use them for 5 days and 2 hours and it only cost you a few hundred dollars.These are spare computing capacities that could be abruptly terminated.
