There's a common theme we encounter here at TeleGeography Explains the Internet.
It goes like this: the enterprise WAN has undergone significant changes in the past several years to align the network with digital transformation, cloud adoption, rising bandwidths, and cost control. These changes—while making the network more resilient and affordable—can introduce new challenges in complexity and management.
Our guest today is Marcel Stadler, Product Manager of SD-WAN at Open Systems.
Marcel joins our semi-annual conversation on this landscape; he outlines how managed SD-WAN providers like Open Systems approach these issues with their enterprise customers. (Yes, we chat about SASE and integrating security into an SD-WAN because we know what the listeners want.)

Where are we building data centers? Why? What markets are primed for interconnectivity glory? Which ones are getting left in the dust?
We've heard these questions again and again. So we did what any reasonable telecom data provider would do: we developed an interactive tool to rank the world's best-connected and fastest-growing cities, scored on a scale of 0-100 across nine key categories.
This week's guest on TeleGeography Explains the Internet is our resident data center expert Jon Hjembo. He walks us through how (and why!) we developed the Market Connectivity Score and reveals what initial rankings tell us about the interconnectivity landscape and metro areas to watch like Kuala Lumpur.

TeleGeography Explains the Internet is back from summer break.
We return a little older, a little wiser, and you can bet that we've done the summer reading. To that end, we're starting this season with a classic TeleGeography Explains deep dive.
The topic? U.S. telecom law!
Greg is joined by Jeff Long, an attorney in private practice with broad experience in both the data center and telecom industry.

Over the past five weeks, we've endeavored to explain precisely how data moves around the world, covering the basics of internet, transport networks, data centers, and the cloud along the way.
Today we answer our final, lingering question: What is a WAN?
First, let's get definitions out of the way. WAN stands for wide area network, which came out of the term LAN, or local area network.
Today's episode will help you brush up on the evolution of the WAN. We'll also hear from Brianna Boudreau, TeleGeography's current SD-WAN guru.

You may have heard a popular saying: There is no cloud, only other people’s computers.
To explain how it works, Senior Research Manager Patrick Christian joins us to talk cloud. We explain what it means to get something "as-a-service," hyperscalers, CDNs, and how companies get to the cloud.

We're back at it with episode three of our five-part podcast special that explains the nuts and bolts of the internet. We haven’t yet covered exactly how and where those networks meet and exchange traffic with each other and access their destinations.
So today, it's data center time.
Senior Research Manager Jon Hjembo was on hand to help us work through data center types, their defining features, and what happens inside these facilities. We talk about who owns these structures and how their geography informs the way the internet works.

Welcome back to our five-part podcast special that literally explains how the internet you know and love works.
Last week we covered the most basic question: what is the internet?
Today, we tunnel deeper, exploring the physical transport networks behind this seemingly invisible, omnipresent information superhighway. Plus we get a little help from TeleGeography's own Paul Brodsky, Peter Wood, and Lane Burdette for this one

What is the internet? Simply put, the internet is a network of computers.
Computers can only understand two things: on and off. Everything that we do on the internet is in binary—a series of 1s and 0s representing on and off—which gives instructions to your computer to do all the amazing things it does.
This means that the very bottom of the internet is a system for sending those 1s and 0s over wires (or spectrum in some cases). Whatever you do on the internet—email, videos, chats—the information is translated into that binary by your devices and then transmitted via packets.
We cover this process and lots more in the first episode of our five-part special to, well, literally explain the internet.

On TeleGeography Explains the Internet, we often focus on the long-haul, zeroing in on the network portion of telecoms. Today, with the help of Tiago Rodrigues, President and CEO of the Wireless Broadband Alliance (WBA), we’re switching things up a bit.
Drawing upon his vast expertise in the Wi-Fi space, Tiago steps into the hot seat to outline the key issues in the wireless LAN.
This episode considers Wi-Fi 6, 6E, and 7 developments, OpenRoaming™ that allows seamless connection across different Wi-Fi networks, and Wi-Fi’s role in emerging solutions like NaaS.
We also discuss the digital divide and how to best use the limited resource of spectrum to ensure connectivity in our increasingly digital world.

Today we welcome Nokia's Paul Unbehagen to the pod.
Paul has a deep history in the networking world, so he approaches his role at Nokia—NE Americas CTO—from the perspective of a network engineer.
Although our main topics this week are enterprise cloud and right-sizing cloud utilization, we use those as a springboard into many topics circling the state of the network in 2023.
We touch on the history of the enterprise’s move into the cloud and why some companies have reevaluated their cloud strategy in recent years.
As it so often does, the geography of the cloud comes up, along with Paul’s take on location and design in the cloud. This brings us to the edge—not only what it means and where it is, but some of the new and exciting use cases of what edge computing facilitates.
Embedded in that conversation is also 5G and how mobile can push the network into being a central part of the business. And we can’t resist bringing up AI/ML.

Today’s TeleGeography Explains the Internet guest comes to the security world with a deep background in cloud and networks.
Joe DePalo is Chief Platform Officer at Netskope, and the ideal person to help us understand how and why location matters in network security.
We first identify how the network has changed over the past few years, gauging the impact on both the threat landscape and how networks perform generally. Also on the agenda: why middle mile performance and security should be part of the equation, and how lessons learned from the challenges of creating CDNs are instructive about the modern issues in network security.
Finally, Joe offers a particularly interesting take on a question that comes up often on the podcast—what does it mean to have a WAN in this environment?
