Real Talk: Are WAN Managers Adopting NaaS?

As cloud adoption becomes increasingly necessary for multinational enterprises, backend networks are becoming more complex.

The introduction of X-as-a-Service products and the need for multi-cloud environments have pushed WAN managers to make changes to their current ecosystems and adopt new technologies.

Let's look at how network professionals are integrating the cloud and Networking-as-a-Service (NaaS) into their enterprise networks.

What Makes a WAN Truly Secure?

I've always known Aryaka Networks as service provider with a different approach to enterprise networks—they don’t neatly fit into categories like facilities-based carrier or managed service provider.

When Aryaka’s Chief Product Officer Renuka Nadkarni agreed to join me on TeleGeography Explains the Internet, I quickly had a list of questions mapped about their place in the WAN landscape.

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.

Never Fear, the 2023 SD-WAN Guide Is Here

The SD-WAN vendor landscape has changed.

Many of the familiar faces that pioneered initial SD-WAN services have been acquired, and a host of managed SD-WAN service providers have emerged as a popular option for many enterprise customers.

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?

Confessions of a Telecom Investor

On TeleGeography Explains the Internet, I typically interview guests who work in the telecom industry or manage telecoms at large enterprises.

Not this week!

Meet Aaron Chan, Founder and Managing Partner at Recurve Capital. As an investor in the “technology media and telecom” space—or “TMT” as they say in finance circles—Aaron has something of an outside perspective.

Preparing the Next Generation of Infrastructure Professionals

Rohan Singh knew his future was in networking and communication when he saw his first network diagram at around 12 years old. That's probably why he feels like he's been involved in networking for most of his life.

Now Vice President of Client Services at Marlabs, Rohan joined us at TeleGeography Explains the Internet to talk about all that goes into the modern digital transformation.

Unpacking Telecom Predictions of the Past

It's one thing to make predictions. It's another to go back and assess how those predictions shook out.

One month into 2023, Mattias Fridström, Chief Evangelist at Arelion, very kindly agreed to scrutinize his 2022 forecast with us.

What Do You Get When You Cross GEO Satellites and SD-WAN?

While most planned satellite constellations used for connectivity fly in low earth orbit (LEO), some fly in geosynchronous equatorial orbit (GEO) and circle the earth from a much further distance.

Because of this distance, LEO satellites tend to have lower latency and higher bandwidth than their GEO counterparts.

So when MetTel tried to cross its SD-WAN offering with HughesNet's GEO connection, it got latency.

More on this story and our other January telecom reading recs below.
