It’s my belief that we will look back at 2017 as a tipping point for the Internet of Things (IoT). IoT has certainly been something that most business and IT leaders talk about, but to date, deployments have been limited to key verticals that have been connecting things for years, although we called it machine-to-machine (M2M) before it became cool to say IoT.

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.

The Gartner Magic Quadrant is certainly the most iconic graphic ever created by an industry analyst firm. Second on that list is the Gartner Hype Cycle. Personally, I find the naming scheme of the elements of the Hype Cycle to be a bit trite, but each phase is fairly accurate.

At the start of the movie Star Trek II: The Wrath of Khan, Lt. Saavik took a test known as the Kobayashi Maru.  The test was actually a trap to see how someone would handle a “no-win scenario” where any choice made would lead to a bad outcome.  In network engineering, a Kobayashi Maru-like scenario is emerging for those who resist a move away from manual processes.

Embracing Automation is Key

One of my new rules is that “manual processes are the mortal enemy of network operations”. Earlier this month I wrote a post discussing the new rules of running a WAN, discussing how manual processes are bad for the business because they make the network a big choke point for the company, stifling business innovation.

Another New Year’s Resolution for Network Managers:
I Will Embrace Virtual Network Functions

In my blog near the beginning of the year, I urged network managers to make a resolution to not stick with the status quo when it comes to evaluating and selecting an SD-WAN solution provider, as it will ultimately prove a bad decision for the company and potentially the engineer’s career.  Another resolution network managers must make in 2017 is to embrace the concept of virtual network functions (VNFs), particularly for branch office and remote locations.

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:
