ABSTRACT
In this chapter, the authors cover fundamentals of edge computing, driving forces for edge computing and edge computing characteristics. One way to split the big bucket of edge computing into more granular segments is the cloud-fog-dew model. Edge computing performs computations in the real-world contexts, responding to physical world data. Although edge computing covers a great spectrum of scenarios, the people can identify some unique characteristics that set edge computing apart from other computing models. Mobile phones are enormously powerful media to bring computing into real-world contexts. Edge computing is very segmented, with many different players at different levels, including cloud platforms, telco companies, hardware manufactures, independent software vendors, standard bodies, content providers, enterprises and consumers. Edge computing has a broad spectrum of application scenarios that have direct impact on making lives better.
