An example system includes one or more users, each user having an allocation of each of one or more resources; and one or more resource brokers, each of the one or more users being associated with one of the one or more resource brokers. A first resource broker of the one or more resource brokers, upon detecting an insufficient allocation of a resource to an associated user, obtains additional allocation of the resource from another user of the one or more users through a second resource broker associated with the another user.
