Computerworld: Amazon Web Services has unveiled a new online marketplace that will allow its customers to resell reserved server instances. Customers who reserve Amazon's cloud computing services receive discounts in exchange for longer-term commitments. For example, you can buy a standard Linux instance for $.08 cents per hour, or you can sign up for a one-year term and pay $69 plus $0.039 per hour. The new marketplace could make those longer-term deals more attractive to organizations because they will have the option of selling their cloud computing time if they don't need it. The marketplace will also likely appeal to potential buyers who need cloud computing services only for a short time but would like lower prices.
Sellers can list reserved instances in the marketplace after they have owned them for 30 days. Amazon takes 12 percent of all marketplace transactions.
