Explaining the Internet Through the Lifecycle of a YouTube Video

Last week, we wrapped up a five-part podcast special that literally explains how the internet works.

This series describes precisely how data moves around the world, covering the basics of internet, transport networks, data centers, the cloud, and WAN along the way.

At the end of each episode, I thought it would be fun to relate what we talked about to a real world example: the lifecycle of a YouTube video.

To paint the full picture, I've compiled each piece of the story here. Keep reading to find out how a video goes from one camera to millions of screens around the world.

For his part, Greg described how the enterprise network has shifted in the last few years, how carriers and enterprises have responded to these changes, and why geography matters in network security.

Inside Asia’s Increasing Demand for Cloud Expansion

In a recent interview with Asian Telecom, I was asked to shed light on Asia’s prominence in global cloud services. More specifically, why are data centers and cloud services expanding so rapidly in Asia?

As population density increases, there is a natural surge in data consumption, like cloud services. So it makes sense that Asia—home to 60% of the world’s population—has a growing demand for data centers.

But that's not the only catalyst here, and there are numerous advantages to having data centers clustered across Asia.
