3 places edge-computing challenges can lurk

How much computing power should we put at the edge of the network?

In the past when networks weren’t supposed to be very smart, it wasn’t even a question. The answer was none. But now that it’s possible to bring often substantial amounts of computational equipment right to the very edge of the network, the right answer isn’t always so easy.

The arguments in favor are simple. When packets travel shorter distances, response time is faster. With compute, storage and networking deployed at the edge, network lags and latencies don’t slow down each trip between users and resources, and users and applications get better response times.

At the same time, because more work is done at the edge, the need will drop for bandwidth between remote sites back and central data centers or the cloud: Less bandwidth, lower cost.
