WAN Manager Podcast 314: Untying the Gordian Knot, Unlocking Your Future Network

June 7, 2022

The TeleGeography team began benchmarking networks almost a decade ago. (Time flies when you're having fun!)

Back then, the big use case was making sure that carrier and customer were on the same page about how much MPLS and access prices had fallen over the life of a contract—and how far prices would probably fall in the next several years.

We still do some benchmarks that look like this. But, more often than not, benchmarking is much more complicated these days.

Enterprises often have some idea of the network they need to accommodate changes in IT—but the path to get from here to there, and the costs of the journey—are far from clear.

To help us bring some order to the chaos, we're glad to welcome back Ian Calderbank of Calderbank Consulting. Ian chats with Greg about legacy networks, related pain points, evolving business needs, and contours of the "target state" network that WAN teams should work toward.

WAN Manager Podcast 313: Very NaaS!

WAN Manager Podcast 313: Very NaaS!

May 3, 2022

Our readers likely know about NaaS: cloud-based network architecture that allows a WAN manager to stitch together different enterprise network components in a self-service, automated way.

At the WAN Manager Podcast, we've been watching the ways in which NaaS has emerged as specific products/solutions from vendors, as well as how it integrates with existing WAN strategies from the enterprise side.
Of course, there's a lot to cut through in terms of how vendors present their services to the market—and what enterprises can actually adopt right now to solve specific problems. 

It only seemed fitting that we welcome back Jason Gintert, CTO and Co-Founder of WAN Dynamics, to the pod to break it all down.

Come for the network-as-a-service talk, stay for Greg's proposed new pronunciation of "NaaS" and the pair's take on if the private WAN is disappearing (gasp).

WAN Manager Podcast 312: SASE Isn’t Revolutionary. It’s Evolutionary.

April 19, 2022

Here's a hot take: the networking hype cycle has moved on from SD-WAN in favor of SASE and now SSE.

To help us navigate how these changes are impacting the modern infrastructure team—especially with respect to SD-WAN—Greg welcomes Nav Chander, Head of Service Provider SD-WAN/SASE Product Marketing at Aruba, to the WAN Manager Podcast.

WAN Manager Podcast 311: Running a Network for a Healthcare Company. During a Pandemic.

April 12, 2022

Two years ago—when the world shut down—WAN managers had to scramble to accommodate massive changes. Offices transitioned to remote work and navigated brand new traffic patterns.

Our guest on this week's WAN Manager Podcast navigated the added challenge of running a network within the healthcare industry, where business needs were changing in real-time.

Carl Flaherty, Manager of Network Services at Main Line Health, shares his network story in our latest WAN Manager Pod.

Greg and Carl talk about pre-pandemic networking, as well as how Carl's team solved the many COVID-related problems thrown their way. This includes setting up pop-up COVID testing sites, preparing radiologists for remote work, and putting out infrastructure fires while social distancing. 

WAN Manager Podcast 310: How Global Events Impact the Internet

WAN Manager Podcast 310: How Global Events Impact the Internet

April 5, 2022

We've discussed the ways in which the WAN is moving away from private networks and MPLS in favor of reliance on the public internet. Not to mention the costs and benefits of that evolution.

Although it's certainly always been the case that WAN managers must stay on top of internet performance and outages, this is increasingly crucial in the internet-first WAN era in which we find ourselves.

To get into the ways in which global events, natural or human, impact the internet—and how to stay on top of those headlines—we welcome a leading expert on this topic to the WAN Manager Podcast.

Doug Madory, Director of Internet Analysis at Kentik, sits with Greg to get into recent world events that have had real, consequential impacts on the internet.

From the volcanic eruption and subsequent tsunami that knocked out internet access in Tonga, to Russia's ongoing invasion of Ukraine and the corresponding information war, the pair had much to talk about.

WAN Manager Podcast 309: How Do You Solve a Problem Like Middle Mile?

March 22, 2022

Coevolve CTO Ciaran Roche is back on the pod. And he's in the hot seat to discuss how middle mile solutions are selected to solve real-world enterprise WAN issues.

When Ciaran joined us last year, we spent lots of time talking about cloud adoption and SD-WAN. You might remember that we discussed how freeing up the transport layer from single-source carrier WANs had created a brand new challenge: how to manage the middle mile.

Almost a year on from that conversation, Greg and Ciaran delve into what we've seen from enterprises who are solving this middle mile problem. The pair get into the use cases for implementing a middle mile solution, related products, and the adoption cycle for middle mile services.

WAN Manager Podcast 308: Data Centers and Digital Transformation

March 8, 2022

When it comes to the cloud and digital transformation of the enterprise, it's always useful to come back to the fact that physical geography matters to our digital world.

Moving the data center off-premises or shifting data and workloads to the cloud doesn’t dematerialize this fact. You still need wires that connect to servers that sit in a rack at a hyperscaler or neutral data center facility.

More than ever, enterprises need to understand the market landscape and pricing structure at what were once “colocation” facilities. (Which were once only interesting to service providers and ISPs.) 

To help us navigate the world of data center operators and pricing, Greg welcomes TeleGeography's resident interconnection expert Jon Hjembo.

WAN Manager Podcast 307: The WAN Managers Have Spoken (For Now)

WAN Manager Podcast 307: The WAN Managers Have Spoken (For Now)

February 22, 2022

We've crunched the numbers from our survey of WAN managers in 2021 and our new analysis is ready and waiting.

What'd we find?

To start, the extended effects of COVID-related remote work have accelerated WAN trends like migration to the cloud, SD-WAN adoption, and incorporating alternative access technologies into the underlay.

Network managers at large multinational corporations are now faced with accommodating a remote-friendly, bring-your-own-device, work-from-anywhere environment. Many will likely be rethinking their network architecture in the coming years, moving closer to internet-first networks and further away from MPLS.

Greg welcomes TeleGeography Senior Analyst Elizabeth Thorne back to the pod to break it all down.

WAN Manager Podcast 306: Integrating Wireless into the WAN

WAN Manager Podcast 306: Integrating Wireless into the WAN

February 15, 2022

One of the earliest and most persistent use cases for SD-WAN has been the ability to utilize alternative connectivity options like internet and fixed wireless. And our WAN Manager Survey data has shown us that, since 2018, MPLS has been losing ground to other wireline alternatives like DIA and broadband.

Over that same period, wireless grew as a percentage of sites in our study—but it still represents fewer than one in ten sites, on average.

That said, we might expect to see that increase significantly over the next few years, particularly as fixed wireless 5G plans emerge.

Founder and CEO of Blue Wireless Ivan Landen joins Greg to discuss how that transition might look.

WAN Manager Podcast 305: Upskilling Network Architects for the Automated Network

February 8, 2022

Network automation pops up often on the WAN Manager Podcast.

But—you know what's under-discussed? The HR aspect of upskilling IT workers and/or acquiring the right talent to make this transformation and manage it going forward.

To get into it, Greg welcomes Michael Martin, Senior Expert of Networking and Network Security at McKinsey & Co.

The pair covers the basics of network automation, getting engineers/network architects up to speed in this area, and attracting the right new talent for these network transformations.
