The Role of Cloud Computing and Fog Computing in IoT

The Internet of things (IoT) is the inter-networking of physical devices, vehicles (also referred to as “connected devices” and “smart devices”), buildings, and other items embedded with electronics, software, sensors, actuators, and network connectivity which enable these objects to collect and exchange data.

The Internet of Things (IoT) is increasingly part of all of our lives, personally and business-wise. An enormous amount of data is also being generated through IoT devices, creating a need for larger data silos and generating more network and internet traffic than before.

Thanks to instruments such as Cloud Computing, we’re able to deliver a variety of data types through the internet to remote data centers.

Cloud Computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand

As mentioned in the Lumen21 blog, without the Cloud, having IoT would be an unreachable dream. Here’s why: All the massive amount of data that gets generated by IoT, won’t be able to travel to its destination without a pathway that Cloud Computing provides for it. These two technologies are inseparable.

The advances in Cloud computing has introduced a new technology, called Fog or Edge computing.

Fog Computing is being used for the processing of data from IoT devices, instead of sending such data to the cloud for processing. It is a model in which data, processing and applications are concentrated in devices at the network edge rather than existing almost entirely in the cloud.

Fog Computing represents a new paradigm for Cloud Computing and involves performing whatever computations that are necessary at the fringe of the Cloud for a host of benefits, including less bandwidth and networking strain, reduced costs, decreased latency, and greater access. Such computing extends the Cloud’s capabilities while decreasing the requirements of the organizations leveraging it.

BI Intelligence, Business Insider’s premium research service, forecasts that 5.8 billion IoT devices owned by enterprises and governments will use fog computing in 2020, up from 570 million devices in 2015. Many IoT devices don’t have their own computing power, and fog computing typically provides a better way to collect and process data from these devices than the cloud does.
