Cloud Rainbows

Cloud rainbow provides resource sharing and manual VM migration between data centers without service interruption.

Cloud rainbow has great significance to resource sharing between data centers located in the same city. For example, when a data center runs out of resources, remodels the building, or updates the hardware, you can migrate some VMs in the data center without service interruption to another data center that resides in the same city and connected to the data center through bare fibers.
