Have some spare computing capacity in your data center, aka the “cloud”? Why not make some scratch by selling it on the open market? Or, if you’re so inclined, you could trade derivatives of cloud computing. In place of mortgage-backed securities, perhaps the world’s banks can pour their savings into another abstract financial instrument that depends on the reliability of Amazon’s web services. What could possibly go wrong?
 
This is the promise of a new exchange for cloud computing capacity, called Cloud Exchange AG, which will launch early next year. It’s a joint venture of Deutsche B?rse, which runs the Frankfurt stock exchange, and software development firm Zimory.
 
Trading computing capacity isn’t as simple as trading, say, wheat. The system implemented by the two firms will allow buyers to specify the location of servers, the precise vendor (e.g. Amazon, IBM, Rackspace), security measures and transfer speed, among other things.
