Trusted execution of a workload payload is brokered among multiple trusted execution platforms. The workload payload is received from a source computing system and includes input data, trusted execution code, and one or more trusted execution policies. At least one of the multiple trusted execution platforms is selected based on the one or more trusted execution policies. A brokered payload is generated to include executable trusted execution code and the input data. The brokered payload is communicated to the selected at least one trusted execution platform. A brokered result generated from the brokered payload by the selected at least one trusted execution platform is received. A workload result based on the brokered result is returned to the source computing platform.
