Putting The Data Center Geography in TeleGeography

When our new WAN Geography Benchmark got a bit of buzz earlier this year, we thought it'd be cool to invite Principal Analyst Patrick Christian back to the pod to explain how this tool was developed.

It's one of those origin stories where a major customer needed to use several of our databases to run a bespoke analysis of their network. The project sparked a bright idea for how to help other enterprises with their data center decision-making.

2021 Trends in Cloud Infrastructure and Global Networks

Any day that ends in "y" is a good one to explore cloud networks. (New TeleGeography slogan?)

But that's exactly what's happening in Patrick Christian's latest presentation, which reviews underlying cloud infrastructure, its evolution, and its impact on global networks. 

The Shifting Connectivity Landscape of Africa

Principal Analyst Patrick Christian boarded yet another plane for Africa last month—this time to Mauritius—to join the 10th Anniversary African Peering and Interconnection Forum.

This year, Patrick's presentation explored the shifting connectivity landscape in Africa and its effect on interconnection hubs, showing that new hubs may soon emerge as more and more cities reduce the cost of connectivity and invest in more infrastructure.

IP VPN, DIA, and EVPN, Explained

What's the difference between VPN, DIA, and EVPN, you ask?

Where to start? Here's are some key definitions that we use in our research.

The Tricky Geography of Enterprise Network Services

It's impossible for every carrier to connect to every city in their customers’ networks. At the end of the day, not all services are available everywhere.

So what does the geographic coverage of enterprise network services actually look like?

Voice Traffic's Slump Continued in a Big Way Last Year

It's true that 2015 marked a turning point in the international voice market—the first time since the Great Depression that international call traffic declined.

All Eyes on the Enterprise: The Latest in Ethernet VPN and SD-WAN

TeleGeography’s Cloud and WAN Infrastructure analyzes service and pricing trends for four key enterprise network services: virtual private networks (VPNs) based on internet protocol (IP) and multi-protocol label switching (MPLS); dedicated internet access (DIA); Ethernet VPN (EVPN); and Ethernet private line (EPL).

This analysis—which has recently been updated with new data—reviews these services and the developing software-defined WAN (SD-WAN) service.

Today we’re sharing the latest on Ethernet VPN and SD-WAN services. Click here to catch up on our recent post about MPLS IP VPN and DIA services.
