Cloud computing provides a promising paradigm for the deployment and utilization of online resources including hardware and software services by Internet users. In such an e-infrastructure environment, the scheduling of user-defined tasks is always considered as a complicated part of the overall system modelling. Specifically, in the case of inter-clouds and inter-enterprises scheduling optimization is fundamentally important for achieving the best possible capacity in terms of resource utilization. Thus, existing approaches that consider system dynamics, interoperability and heterogeneity issues become important aspects for providing advanced scheduling decisions. In this work, we survey some highly dynamic meta-schedulers that are suitable for enterprises using grids and/or clouds. Our intention is to elicit the characteristics and produce a model encompassing the architectural requirements that will enable high meta-scheduling performance in inter-cooperative e-infrastructures.
