SD-WAN Trends: 2020 vs. 2022

Approaching a decade since SD-WAN emerged as a networking technology, it is safe to say nearly all corporate network managers have at least heard of SD-WAN.

The COVID-19 pandemic forced IT infrastructure teams to accommodate remote work and accelerated the shift to cloud services. These changes in the underlay shifted the cybersecurity threat landscape and drove SD-WAN vendors and customers to focus more on security than ever before.

SD-WAN is becoming more complex, integrating SASE architectures and improving services to meet the needs of the WAN world.

When we first asked our WAN Manager Survey respondents about SD-WAN in 2018, interest was high, but few respondents had installed the technology or begun the rollout process.

Over the past four years, early adopters who finished their deployments have started to assess the impact, and more enterprises than ever are in the rollout stage. We’ve looked at the enterprise SD-WAN market every two years to see what has changed and solidified.

When Carriers Collaborate

Wanna look at some cool voice data?

The recent expansion of the i3forum's Insights tool has quite a bit of that. I've been itching to talk about it on TeleGeography Explains the Internet. So today we're chatting with the i3forum, a nonprofit industry body focused on "accelerating transformation across the carrier ecosystem."

Put another way: this consortium of carriers routinely collaborates on solving some of the biggest challenges facing their industry. And they have a really innovative way of sharing data among participants, to the benefit of all involved. (Non-members can participate in this data-sharing, too. More of that in our discussion.)

So in a world where information is power, a new hero has risen to provide SD-WAN vendor knowledge to those in need: TeleGeography’s 2023 SD-WAN Guide.

WAN Configurations Are Shifting

Network underlays have been in transition as more enterprises install SD-WAN services and attempt to meet the increase in cloud traffic. Companies are looking to lower costs and increase connectivity while maintaining secure networks.

All of these changes have led to a decrease in MPLS usage, but has the decline in MPLS stalled?

Behind the Seas: Making Our Famous Submarine Cable Map

There's a good chance that you first heard about TeleGeography through one of our maps.

Our own Research Analyst Lane Burdette was introduced to TeleGeography when she came across our Submarine Cable Map a few years ago. Now part of the team that creates this resource, Lane is understandably stoked about this week's 2023 Submarine Cable Map launch.

It seems like the perfect time to welcome Lane—along with our incredibly talented Designer and Cartographer Larry Lairson—to TeleGeography Explains the Internet.

Disruptions in the Data Center Market

The global data center market is under an unprecedented squeeze as we move into 2023.

On one hand, we have a long-term challenge surrounding the sustainability of the industry’s growth trajectory in essential hub markets. On the other, we have an acute short-term problem with energy prices in the colocation sector.

These issues combine to create an uncomfortable phase in the market right now.
