Edge computing is a return to “distributed computing,” where processing power is spread out over multiple computers. You might think cloud computing is a form of distributed computing too, considering that the cloud can route your request to an available server.

It’s actually not: that server itself is still handling all the computing work on a single machine.

Why edge computing? As devices become more powerful, they’ll require ever-larger streams of data to operate, making cloud computing simply too slow.

Even with superfast 5G connections on the horizon, there will always be some degree of latency in the connection itself. That’s not including the processing time on the remote server.
