    • EC2 uses Xen virtualization. Each virtual machine, called an "instance", functions as a virtual private server. Amazon sizes instances based on "Elastic Compute Units". The performance of otherwise identical virtual machines may vary. [1], the following instance types were offered: * On-demand: pay by hour without commitment * Reserved: rent instances with one-time payment receiving discounts on the hourly charge * Spot: bid-based service (runs the jobs only if the spot price is below the bid specified by bidder — the spot price is claimed to be supply-demand based, however, research refutes this claim )
