Cloud is very important because IoT devices, sensors, and different types of devices process a tremendous amount of information and finally that information has been processed and that is the reason that cloud came into existence. All this information will be sent to the cloud for further refinement and so on. The main issue with the cloud in the IoT environment is the information transmission speed. Let us say there is a cloud and there are different IoT devices deployed. Each of these devices sends all these data to the virtual cloud for further refining and storage. Now, that becomes a problem because these IoT environments have constraints concerning bandwidth, degree of processing, memory utilization, energy consumption, etc. This processing can be handled with the help of the cloud but what about the bandwidth what about the energy consumption because what is going to happen in this sort of scenario of the use of cloud in the IoT context is a lot of data is going to float all around. Over the network, a lot of information is going to be dispatched to the cloud and that will unnecessarily consume the bandwidth and the limited energy that is resident in all these devices. IoT devices have to sense the physical phenomena occurring around them and send the data to the cloud and get an action or comment back. There is a need for fog computing to reduce latency. cloud servers might be physically located in different continents, cities. This physical limitation also introduces a large latency in communication
