Cloud computing provides processing power in form of virtual machines. This processing power can be given to very big and small devices. Similarly for providing processing power, devices with small or big processing power can be utilized. These devices can also be ubiquitous computing devices. Ubiquitous computing devices present in environment may communicate with each other. Ubiquitous computing devices may also share load with each other. Spare processing power of these devices can also be used for cloud computing. An old, less powerful computing device which is capable of connecting with Internet can avail processing power of new computing devices.
