Amazon on Thursday announced reserved pricing for its EC2 instances. Simply put, customers can reserve instances for one-year and three-year terms as if they owned the hardware. Enterprises can guarantee they have an EC2 instance for computing power they know they’ll use and buy on the spot market to account for spikes at the usual Amazon rate. Under Amazon’s model, customers only pay for the computing power they use even if instances are reserved.
