In our latest episode of the WAN Manager Podcast, 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.
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 seems like a good day to unveil our 2021 Submarine Cable Map, don't you agree?
We often say that we'll be taking a "deep dive" into an issue at the beginning of our WAN Manager Podcasts. Today we almost mean that literally, as Greg welcomes TeleGeography Research Director Alan Mauldin to talk about submarine cables.
We're going back to the middle. The middle mile, that is.
Like many telecom terms, this is one that you might have to follow up with “what exactly do you mean by that?”
The average enterprise network had MPLS running at 82% of sites in 2018. That fell to just 58% in 2020. About one-third of those networks have active backups for their MPLS service—a quarter of them have passive backups.
Looking at these numbers, we have to ask: what role will MPLS play in the WAN moving forward?
Look alive. Our latest episode of the WAN Manager Podcast is all about network monitoring.
Step right up. Today we're touring TeleGeography's latest Global Internet Map. (For your safety, please keep your hands, arms, and legs inside the vehicle at all times.)
