Axios has a post on YouTube replacing textbooks in classrooms across America.

In the Pearson study that Axios references you can see YouTube moving ahead of printed books as preferred ways of learning.

As Sal Khan the Khan Academy has made the point that his cousins would rather watch him on YouTube than talk to him in person. This YouTube video explains this insight.

New Video coming out Paris to Pittsburgh as a rebuke of Trump pulling out of Paris accord

I have been writing about Green Data Centers so long that when I started no one was committed to be carbon neutral.  Now it is so common I don’t even treat it as a news anymore. What did catch my eye is Bloomberg choosing to release a video in response to Trump pulling out of the Paris Accord. Here is a teaser that I found in this Axios post.


System Innovation and part Edge Data Center plays, Part 5

Many think of the edge locations as an obvious move to improve the performance of services that benefit from low latency like cellular networks with edge data centers. The cellular site and its role in the overall system is complex and hard for most to understand how it works. Below is a video on system innovation that goes over some of the concepts that experienced system architects think about.

New and Old Networking Topology for Edge Data Center's for Cellular, Part 4

Most who are working on edge data centers are not networking people and edge data centers are  thought of an expansion of existing data centers. An example is the application to Cellular Sites/Towers and many thinking that micro data centers will show up at all the cellular sites and many more will show up.

Data Foundry has a nice post on Edge Data Centers.

data processing power at the edge of a network instead of in a cloud or a central data warehouse.

This is a common description of what the edge data center is. But what few ask is what is the network topology for edge data centers. below is an example of cellular network.


When you look at this diagram there are many that assume that the complex network is bypassed by putting content on the edge.

As part of the movement to 5G there are many changes coming which includes a Network Function Virtualization. If you think the cellular network is going to change to support 5G, then check out this Network World post from 2014.

Clos networks is one of those enduring concepts that we will undoubtedly see again and again in the evolution of networking technologies.
