The substantial growth of the distributed computing using heterogeneous computing has enabled great expansions inCyber Physical Systems(CPS). Combining CPS with heterogeneous cloud computing is an alternative approach for increasing sustainability of the system. However, execution of resource management in cloud systems is still encountering a few challenges, including the bottlenecks of the Web server capacities and task assignments in the heterogeneous cloud. The unstable service demands often result in service delays, which embarrasses the competitiveness of the enterprises. This paper addresses the problem of the task assignment in heterogeneous clouds, which is proved as a NP-hard problem. The proposed approach is calledSmart Cloud-based Optimizing Workload (SCOW) Modelthat uses predictive cloud capacities and considers sustainable factors to assign tasks to heterogeneous clouds. To reach the optimization objective, we propose a few algorithms, which includeWorkload Resource Minimization Algorithm(WRM),Smart Task Assignment (STA) Algorithm, andTask Mapping Algorithm(TMA). Our experimental evaluations have examined the performance of the proposed scheme.
