In-house servers

It is likely that a move towards Internet of Things in the near future will A. Increase the utility of clouds, because the IoT devices will generate a huge amount of data that will be processed by the clouds B. Decrease the utility of the clouds, because IoT brings computational power closer to the user, while cloud computing is far from the user C. Have no effect on clouds, since they are totally unrelated technologies

Increase the utility of clouds because the IoT devices will generate a huge amount of data that will be processed by the clouds
