1. A method comprising:

  • establishing, by one or more hardware processors of a cloud device that is included in a cloud computing environment, a local forwarding function in a virtual machine of the cloud device,the local forwarding function connecting the cloud device with one or more local devices associated with the cloud computing environment;

    establishing, by the one or more hardware processors of the cloud device, a global forwarding function in the virtual machine of the cloud device, the global forwarding function connecting the cloud device with one or more global devices associated with one or more other cloud computing environments, the global forwarding function interconnecting the cloud computing environment and a particular cloud computing environment of the one or more other cloud computing environments, the cloud computing environment being dissimilar from the particular cloud computing environment, and the global forwarding function enabling a bridge for broadcast regions in the cloud computing environment and the particular cloud computing environment;

    using, by the one or more hardware processors of the cloud device, the global forwarding function to create a mapping of local trunk ports, of the cloud computing environment, onto global trunk ports;

    establishing, by the one or more hardware processors of the cloud device, a virtual control plane in the virtual machine of the cloud device,the virtual control plane controlling the local forwarding function and the global forwarding function;

    communicating, by the one or more hardware processors of the cloud device and via the local forwarding function of the cloud device, first traffic with a particular local device of the one or more local devices; and

    communicating, by the one or more hardware processors of the cloud device and via the global forwarding function of the cloud device and based on the mapping of the local trunk ports onto the global trunk ports, second traffic with a particular global device of the one or more global devices.
