1. A method, comprising: identifying, by a processor, within a multi-level service level agreement (SLA) for a cloud network, a first commitment level indicating a first amount of resources needed by a first amount of instantiated virtual machines and a second commitment level indicating a second amount of resources needed by a second amount of instantiated virtual machines, the cloud network provided by a plurality of providers and including at least two providers; detecting a triggering event that indicates a change should be made from the first commitment level to the second commitment level; generating a resource aggregation table comprising a plurality of sets of resources in the cloud network, each set of resources from a provider, the resources in the set of resources in conformance with the second amount of resources identified by the second commitment level; selecting at least one set of resources from the plurality of sets from a first provider to meet the second commitment level; and adjusting, by the processor, resources used within cloud network from the first commitment level to the second commitment level using the selected set of resources in response to detecting the triggering event.
