Evolve Your WAN to Be Truly Software Defined: The Hybrid Approach to SD-WAN

Evolve Your WAN to Be Truly Software Defined: The Hybrid Approach to SD-WAN

IT leaders recognize the value of software-defined wide-area networks (SD-WAN), and when it comes to implementation, 80 percent of executives are opting to augment rather than replace their network technologies, according to a new IDG Market Pulse survey. This is called a hybrid SD-WAN approach, and the advantages are clear.

By implementing SD-WAN in a hybrid fashion, IT leaders can strike a balance between price, performance, and risk tolerance. Hybrid SD-WAN solutions empower enterprises to still leverage their existing networking investments while also customizing WAN connectivity by application, by user, and by location. The result is a highly-flexible solution designed for your specific needs.

Much of the initial marketing hype surrounding SD-WAN led IT folks to believe that they had to make a binary decision with MPLS for example. The fact is, it’s NOT an SD-WAN vs. MPLS situation. While, yes, SD-WAN technically can be a “rip and replace” solution, the Market Pulse research shows only 20 percent replace their network with SD-WAN. Indeed, Masergy’s customers follow the same pattern. We find that in most enterprise use cases, MPLS and SD-WAN can and should coexist.

 

While buyers are excited about the agility and flexibility that hybrid SD-WAN solutions offer in today’s rapidly changing world, many are still concerned about configuration and maintenance; the breakdown is as follows:

  • 51 percent - interoperability
  • 51 percent - costs
  • 48 percent - skills needed for implementation

This is where managed service providers, like Masergy, can assume control with a turnkey solution. With Managed SD-WAN--just like that--you can get all the SD-WAN advantages with none of the headaches. While critics might say “this sounds like some hocus pocus,” it’s true. Here are two key ways Masergy makes it easy:

  • Benefits without Risks: Most SD-WAN vendors want to sell you a box that you’re expected to deploy on each site and manage yourself. Masergy Managed SD-WAN is different. Our fully-integrated managed solution lets you add SD-WAN where and how it best fits on your network.
  • It’s Never Either/Or: Through native integration with our global Software Defined Network Platform, deploying a custom hybrid SD-WAN solution has never been easier. And, with our access-agnostic approach, you can mix and match access options to strike the optimal balance among price, performance, and resiliency. With Masergy SD-WAN, it’s never an either/or proposition: the choice is yours.

The Takeaway: When plotting your path to SD-WAN, understand the benefits of a hybrid architecture and understand that the feature comparison checklist is only part of the equation. Select a service provider who understands your IT innovation agenda and business goals while evaluating applications, users, and locations to design the perfect network solution for you. Stay focused on your mission: striking the optimal balance between price, performance, and resiliency to ensure your applications deliver the right experience for your users.
