It’s safe to say that no one likes change. It makes us uncomfortable and puts us in positions that we are not familiar with. This is certainly true in our personal lives, but it’s also true in our jobs. It seems every time there is some kind of major technology shift everything changes, and IT needs to adapt, adopt new best practices, and develop new skills. Think back to the transition from mainframes to PC computing, TDM voice to VoIP, and physical servers to virtualization. Each of these seismic shifts required IT organizations to completely change the way they operate.

In my last post I focused on how managed SD-WAN service providers can help large, distributed organizations with the complexity of managing dozens of relationships with various broadband providers. This can let a business with hundreds or even thousands of locations enjoy all the financial and performance benefits of SD-WANs without the associated risk of having to find and procure services from a bunch of DSL, cable, Ethernet, or other types of transport providers, since that’s one of the roles to managed service provider will play. This post will focus on the evaluation criteria that decision makers should use when choosing a managed service provider for SD-WAN. Below are what I believe are the top criteria:

Highly-Distributed Organizations Should Consider
Managed SD-WAN To Accelerate Adoption

There is no company too small or large to take advantage of Software-Defined WAN (SD-WAN).  The only requirement is the obvious one that the business be multi-site in nature and is running a WAN that connects the locations together.  However, not all WANs are created equal.

Earlier this week I wrote this post on the reasons why it is important for network managers to embrace automation. My argument revolved around the fact that network changes can be made much faster and far more efficiently through the use of automation vs. trying to manage the network a device at a time. This is particularly important for the WAN as the network endpoints are located all over the globe and errors can result in lengthy outages. SD-WANs change the networking paradigm and make automation a reality.

When discussing the value of an SD-WAN, many points enter the discussion. Cost comes up as SD-WANs are certainly cheaper. Delivering a better and more predictable user experience is another reason to adopt an SD-WAN, since users will certainly experience better application performance and, in turn, become more productive. But a third element that’s not talked about as much is the automation that SD-WANs bring to networking.

Merriam-Webster defines the word “conundrum” as an “intricate and difficult problem”. This word can most certainly be used in a business context to describe the challenges associated with providing Internet access to branch and remote office workers. Legacy networks provided Internet access to users through a hub-and-spoke architecture — Internet connectivity came into the hub and then was distributed out to the branches via the spokes. This was never an ideal method of delivering Internet services since the traffic effectively traversed the WAN twice (to the branch and back); most companies lived with it, though, as Internet access wasn’t considered mission critical in the mid-90s.
