Abstract: Technologies are described herein for providing a marketplace for the remaining term of reserved instances. A selling customer identifies a reserved instance of a computing resource for which the customer wishes to sell a remainder of their term and specifies an asking price. A reserved instance listing associated with the identified reserved instance and asking price is created. A buying customer provides a specification of reserved instances that they wish to purchase, including a term. The specification may also include size, platform, tenancy, availability zone, and other parameters of the reserved instances. The reserved instance listings are searched to find associated reserved instances matching the specification and having a remaining term equal to or greater than the term in the specification. The reserved instances associated with the reserved instance listings having the lowest asking price may then be transferred from the selling customer to the buying customer.

Abstract: Methods and apparatus for a job resource planner for cloud computing environments are disclosed. A system includes a plurality of resource instances of a provider network, and a resource planner. The planner receives a plan request from a client, comprising a job goal and an indication of a resource acquisition policy to be used to obtain resource instances for the job. The policy specifies one or more instance data sources. The planner generates a resource acquisition plan for the job, based at least in part on an analysis of pricing data obtained from a specified data source. The analysis comprises one or more computation steps indicated in the policy. The generated plan includes at least one recommended acquisition price for a resource instance.
