An embodiment of the invention includes a method for workload optimization in a network (e.g., cloud computing environment). Usage of resources in the network is monitored in order to maintain a metadata catalog of operating experiences of the resources. A request for a resource in the network is received; and, resources that are available in the network are identified. Units that are included in the resources are also identified. The metadata catalog is queried for operating experiences associated with the requested resource. The requested resource is provisioned by the host system based on the operating experiences associated with the resource. This includes assembling the units that are included in the requested resource and/or automatically allocating workloads of the computing modules based on the cataloging of the workloads in the metadata catalog. The metadata catalog is updated with an operating experience associated with the provisioning of the requested resource.
