When we reached out to today's podcast guest—Jim Poole, Vice President of Business Development at Equinix—about being on the show, we asked if he'd be willing to dig into NaaS or edge data centers. But as we got to talking before our interview, we realized that these two topics are deeply interrelated. And Jim has lots of insight to share about where the market is headed. We waded through how Equinix is approaching NaaS from a solutions standpoint and what it means to truly be an edge data cente...

Anyone in the WAN business—from the carrier or end-user side—knows that local access can present some of the biggest challenges in corporate networks. There's a physical geography problem that's not easy to overcome. We're talking about pulling and maintaining wires to all corporate sites, which is especially challenging when customers need physical diversity and protection. Wireless has long been a backup of last resort for many users, but 5G has presented the promise of relieving this pain poi...

While NaaS and the middle mile are fairly new concepts, they're not new to the podcast. In episodes past, we've highlighted the framework, concept, market players, and products available. Now we consider things from another perspective. Ameet Naik, Director of Product Marketing at Cloudflare, takes center stage to help us tackle some real-world NaaS use cases.

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 ide...

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. 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 ac...

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 episode 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 pod. Greg and Carl talk about pre-pandemic networking,...

Although WAN managers have always had to be aware of internet performance and outages, this is increasingly crucial in the internet-first WAN era. To explore how 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 show. 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. The pair had much to talk a...

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 wh...

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...

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 l...

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 signif...

Network automation pops up often on the pod. 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. Greg welcomes Michael Martin, Senior Expert of Networking and Network Security at McKinsey & Co to get into it. 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 tran...

We're going to talk about the cloud. More specifically, cloud outages and how to avoid them and mitigate their impacts. There's no way we can dig into this topic without touching on multicloud strategies. Even back in 2019—when we surveyed WAN managers about their organization’s cloud infrastructure—we found that three in four enterprises had already gone multicloud, with at least two IaaS providers. We also found that the majority of enterprises were in hybrid cloud situations, with some mix of...

If you caught last week's special episode of the pod, you must be waiting on the edge of your seat for the second installment. To recap, Greg Bryan and Elizabeth Thorne are keeping up their tradition of decking the halls with an end-of-year WAN review. And since 2021 was such a big year, we couldn't fit everything into just one episode. To compensate for the cliffhanger, we've packed part two with enough data and lively conversation to knock your stockings off their mantel. We're talking 5G depl...

In this podcast holiday special, we're shaking the snow globe that is the 2021 WANscape. Greg welcomes back TeleGeography Analyst Elizabeth Thorne to present another year in review. To keep the conversation on track, Elizabeth made a list (and checked it twice), but we couldn't fit everything into one episode. Part 1 covers SASE adoption, SD-WAN maturation, how remote work is changing the face of corporate networking, the evolving MPLS vs. DIA matchup, and more. We'll be back next week with Part...

While a fifteen-year friendship with Greg is not a prerequisite for guests on the pod, it sure makes for good conversation. To kick off Season 3 of the pod, Greg calls on longtime colleague Rob Schult, who also happens to be a Research Director here at TeleGeography, to draw a connection between the wholesale and enterprise retail markets. What should IT infrastructure and sourcing teams pay attention to in the wholesale market? You’ll also hear about IP transit and why the vast majority of ente...

When TeleGeography started tracking the SD-WAN market in 2017, we found dozens of vendors with a service they were calling "SD-WAN." But are all of these services created equal? What does it take for your solution to qualify as SD-WAN? Today we pull back and discuss SD-WAN definitions and certification. Greg aims to better understand the exact definition of SD-WAN and how related certification can benefit both end-users and managed service providers. And for that, we're so glad to welcome a true...

Are you like the (approximately) half of our survey respondents who have not yet adopted SD-WAN? Or perhaps you're in the midst of deployment and want to know what to look out for. Or maybe you're working out whether or not to keep MPLS? Today we'll share some perspective on these questions with another case study, this time with Mark Williams, Sr. Manager of Global Networks at BorgWarner.

Today we're living on the edge! Whether we're talking security and SASE, NaaS, or cloud computing—or many other topics, honestly—edge networks and edge computing are likely to make it into the conversation. Greg welcomes two experts from Catchpoint to help us dig in: CEO Medhi Daoudi and VP of Operations Tony Ferrelli. Medhi's recent blog post Monitoring at the Edge of the Third Act of the Internet sets the tone for a great conversation, spanning enterprise apps, network monitoring, and the geog...

It's another case study episode of the pod. Today, we welcome Ian Calderbank, Enterprise Network Architect at PageGroup, to the hot seat. In his conversation with Greg, Ian details the network transformation process for a multinational staffing agency. An environment packed with knowledge workers and downtown office space sounds like an enviable position to be in as a WAN manager, right? But there's no shortage of lessons learned as the pair gets into pre-SD-WAN solutions, organizing major netwo...

In this episode, we dig into sourcing. Our listeners know that we often discuss the migration of large enterprises away from one or two global suppliers for a mostly MPLS network to a novel mix of transport types and suppliers. This is especially true due to changing trends in cloud migration, SD-WAN, and security. May it be local internet breakouts from a variety of ISPs alongside MPLS or sourcing a backbone between data center nodes, many enterprises have taken on a “telco-like” role in buying...

Our data shows that a majority of enterprises have more than one IaaS provider. For SaaS, that number can be dozens, hundreds, even more. And most have moved the majority of their data centers off corporate premises to some kind of shared facility. This means most companies are dealing with multi-cloud connectivity in some shape or form; WAN managers of course have to handle that from a performance and cost perspective. Today we hear from a data center insider, diving into network-as-a-service m...
