Edge computing in the 5G era.

What is edge computing? What are use cases that will benefit from edge? What are the opportunities and threats for mobile operators in the 5G era? There has been a lot of discussions about 5G in the recent few years, however, mobile operators will only deliver incremental value if they have a combined 5G and edge computing strategy. Also, although mobile operators will be important players in the edge space, they will not be the only ones and unless the move up the value chain they will not get the full benefits that edge will provide.
