I attended Internet of Things World in Santa Clara, Calif., this week and served as the track chairman for, you guessed it, cloud and IoT. The vibe I got throughout the event was one of confusion: IoT seems to be so systemic, yet is difficult to define. As one presenter put it, “It’s like plastic. It’s going to be a part of everything.”
In the context of the Internet of things, the trouble with the cloud is that data needs to be sent back from the sensors gathering info, such as a Nest thermostat or a Fitbit, to a database in a remote public cloud. The time that it takes for the data to be transferred from the device or sensor to the remote public cloud — that is, the latency — is often too much to meet the requirements of the IoT system.
