Discover fog computing, a decentralized network design that transports computing resources and application services closer to where the devices use the data.
- The internet of things is expanding and creating opportunities in many different areas and will shape new business models that meet customers' needs. Opportunities, productivity and growth all rely on data. Devices in the IoT are constantly gathering data. After collection, they send the data to the cloud, which is a network of servers in another location providing centralized resources such as computation and storage.
Businesses use a good deal of the data gathered for statistical analysis, forecasting and data analytics. The cloud is a resource somewhere else, and the problem with the cloud is simply distance. Cloud servers have the power to process and mine large data sets but are too far away to process data and respond in real time. Because of the distance, the cloud model can be a problem in environments where operations are mission-critical or internet connectivity is less than ideal.
An optimal solution is to distribute the computing requirements and bring processing closer to the edge of the network, reducing the amount of data that is sent to the cloud for processing and analysis. There is a huge value in having access to real-time information and analytics from device-generated data, which helps businesses to make critical split-second decisions. Bringing computing resources and application services closer to the edge is fog computing.
Fog computing is the combination of hardware and software solutions that decentralizes the cloud, monitors and analyzes real-time data from network-connected things and then takes action. The fog reduces data-analysis time from minutes to seconds. Situations where milliseconds can have fatal consequences require high-speed data processing such as diagnosis and treatment of patients or vehicle-to-vehicle communication to prevent collisions and accidents.
I'm at the OpenFog Consortium, which is a group of developers, manufacturers and software companies that share ideas on how to expand the use of the fog for the internet of things ecosystem. Fog computing supplements the cloud and will continue to expand as it improves efficiency and reduces the amount of data processed by the cloud.
Lisa Bock kicks off the course with an overview of IoT, and the types of IoT devices designed to improve the quality of life in homes and businesses. Lisa covers different networks that range in size and purpose—LANS, WANS and PANS—and explains how businesses invest heavily in IoT in order to keep a competitive edge, going into IoT developments in automobiles, building automation, and the medical field. She then evaluates consumer devices, such as wearables and mobile devices. Plus, she discusses zero-configuration networking, service discovery, designing IoT security, and more.
