1. A method comprising: in a cloud computing configuration system, with cloud control circuitry: determining to implement a cloud architecture by deploying instances of a workload component; determining constraints applicable to the workload component; determining capabilities of available cloud computing platforms hosted by different providers; selecting deployment cloud computing platforms from among the available cloud computing platforms responsive to the constraints applicable to the workload component and the capabilities of the cloud computing platforms; and with instantiation circuitry: initiating deployment of the instances of the workload component to the deployment cloud computing platforms, where multiple different providers host the deployment cloud computing platforms.
