Considering Cloud Connectivity Providers

If you’re an enterprise network manager in need of a dedicated cloud connection service, you’re in luck; you’ve got a wide array of service providers and locations to choose from. 

You could set up a link directly with the cloud provider, but why not use a third-party—such as a carrier, colocation provider, or connectivity specialist?

The question then changes. Who are you going to choose? And where will you set up your connections? This often depends on the location of your enterprise WAN in relation to the cloud providers’ regions or data centers.

In this analysis, we’ll explore options available to network managers.

Global DIA Prices and Trends

In a recent analysis, we highlighted how DIA has gained ground as an integral part of the global enterprise WAN and how it compares in price directly to MPLS.

However, it is not just a matter of switching underlay products, but also understanding the global pricing dynamics of those alternatives.

What Problem is the Middle Mile Trying to Solve?

As global enterprises become more reliant on cloud—and start to break away or reduce their traditional MPLS circuits—the “middle mile” of the internet is coming into focus. 

Today, I want to examine the use cases that vendors hope to address through middle mile network services. (And their basic value proposition.)

WAN Pricing Over Time

We've written before about how prices vary by geography. 

Well, it almost goes without saying that they also change over time.

Underlay Changes: MPLS vs. DIA Pricing

In the past few decades, the corporate WAN has undergone a few massive reformations.

Three Facts From Our New WAN Market Size Report

If you've perused our research catalog lately, you'll know that we have a new WAN Market Size Report.

In this offering, we present a data-driven, granular view of market opportunity for underlay of the corporate WAN. (More about that here.)

To understand where the larger multinational WAN market stands today, we're sharing three takeaways from the first edition of the WAN Market Size Report.

New WAN Market Size Report Shows a Global WAN Market Worth $75.9 Billion

There’s no question that the enterprise wide area network (WAN) market is in a state of flux. 

We’ve seen multiple disruptions in the way multinational corporations construct WANs: a move toward cloud computing, migration of the data center away from corporate premises, and, especially, the introduction of SD-WAN.

To help carriers, vendors, and enterprise IT infrastructure teams understand how these changes will affect the business of telecom, we’ve created the new WAN Market Size Report.

WAN Pricing Mythbusters: Do Tier 1 Carriers Charge More for DIA?

My colleague Elizabeth Thorne and I have been working on busting–or confirming–WAN pricing myths that we’ve heard in the wild. Last time I took on MPLS and DIA price convergence. 

I’m going to stick with DIA for this post, too.

Specifically, I want to know if Tier 1 IP providers charge more for DIA service than others. This is a myth I’ve actually argued in favor of in the past. It is certainly true that some carriers can provide a higher level of service, i.e. traffic that takes the fewest hops between destinations, and maybe even traffic that never touches another provider’s network. This might warrant higher prices.

WAN Pricing Mythbusters: Is MPLS Priced Like DIA?

In case you missed my previous post, we here at TeleGeography love busting telecom myths. But we haven’t turned our analytical tools toward common WAN pricing myths—until now! 

In this second installment, I’m going to investigate whether MPLS IP VPN and dedicated internet access (DIA) prices have become one and the same.

WAN Pricing Mythbusters: Is Local Access 50% or More of the WAN?

We have a years-long tradition of Mythbusting here at TeleGeography. But it occurred to me that we’ve never tackled any of the WAN pricing myths floating around out there. That’s why I decided to do a series addressing some of the things I hear from WAN-sourcing and WAN-selling professionals. 

Let’s see if these WAN pricing myths stack up against the data. 

First up: is it true that, particularly for traditional MPLS networks, local access can account for upwards of 50% of the total cost of ownership (TCO) of WAN components?
