Abstract: A computer-implemented method that identifies resource efficiency deficit score infrastructure resources in cloud environments based on attributes that influence carbon emission controls at least one of the infrastructure resources based on the infrastructure resource efficiency deficit score of that the infrastructure resource. The infrastructure resource efficiency deficit score can equal BVt/(WBt+BVt), where BVt is a best value point and WBt is a worst value point. According to other illustrative embodiments, a computer system and a computer program product for identifying resource efficiency deficit score infrastructure resources in cloud environments are provided.

Abstract: Selected resources that satisfy a specified technical requirement are entered into a selected pool as a function of a sourcing rate, a screening rate and a selection rate that are each variable over time and applied during a sequence of selection time periods that span a demand forecast time period. Offers for acquisition are iteratively made to the selected pool of resources in a sequence of different offer time periods, wherein the resources are progressively moved into different awaiting offer buffers after each of the offer time periods. The demand number is re-forecast and one or more of the sourcing, screening and selection rates adjusted to minimize a combination of costs of the rates with a cost of acquiring resources to satisfy the gap number as a function of the demand number.
