Why should IT seek to understand the WAN market? If you are a decision-maker for the organization or involved in influencing the choices your organization makes about WAN infrastructure, then you may have an outsized influence on the ability of your enterprise to function and your business to reach its goals.

The enterprise WAN is the backbone of every organization. And if you choose the wrong solution for your enterprise’s evolving needs, that backbone becomes unwieldy or unstable – creating more work for your team and expanding the budget needed to maintain the network.

Understanding the market – and what factors into the predictions about market growth – helps you make better informed decisions about which solutions will provide you with the largest ROI in terms of budget, effort, and longevity. In this whitepaper, we’ll introduce you to the SD-WAN market and to the various types of SD-WAN solutions available.

How big is the SD-WAN market, really? It depends on whom you ask:

  • According to Gartner, by 2020, SD-WAN will be a $1.1 billion market.
  • But P&S Market Research throws cautious predictions to the wind, suggesting that by 2022, the market will be at $9,378.6 billion.
  • In that same vein, Research and Markets puts the SD-WAN market at $7.53 billion in 2021, and IDC comes in close with a prediction of $6 billion by 2020.
  • IDC also speculates that, based on U.S. survey data, nearly half of all enterprises will be considering a migration to SD-WAN next year, while Gartner sees only 25% of enterprises adopting it in the next two years.

SD-WAN is a response to the shift in business application architecture from the data center to the cloud, allowing enterprises to connect their end-users in a safe and reliable way to their third-party cloud platforms and SaaS applications.

However, SD-WAN isn’t, in most cases, as simple as just a software-defined on-ramp to a private network – it comprises both hardware and software, and the methods in which it is delivered and by which it performs differ from company to company.

The large number estimated by Research and Markets included:

“SD-WAN hardware that includes appliances and routers, SD-WAN software that includes orchestrators, gateways, cloud routers and firewalls, dashboards, management systems among others, and SD-WAN services that includes Service Provider Managed SD-WAN services and Cloud Managed SD-WAN services.”

The Gartner report details sixteen different vendors, and no two are exactly alike. Some offer overlay and others in-net; there are both regional and global SD-WAN; and you can pay for a managed service or provision the extra resources to do it yourself. So how are you to make heads or tails of which solution is right for you?

DIY or as-a-Service?

Some IT departments prefer to construct their own network, as opposed to consume a ready-made model.

Even in a DIY situation, WAN management software from DIY SD-WAN vendors can make the orchestration of network services easier at the branch; however, the IT department then must deal with multiple vendors and contracts. In this case, the management of these networks becomes resource-intensive, and integration of new branch offices or links can become a hassle, especially when dealing with large global network scenarios.

In the as-a-service or cloud-based OTT model, the solution is fully integrated. WAN management is taken care of by the as-a-service SD-WAN provider, freeing up IT resources and budget for other projects.

While the consume model is not for every enterprise, some SD-WAN providers make it possible to customize the services delivered to meet the needs of the purchasing organization in order to best meet their needs with a complete solution.

Regional or Global?

Most SD-WAN can still only support regional deployments because they rely only on the Internet and don’t include custom-built private networks for fast cloud and SaaS connectivity. Although it can reduce network complexity and lower network costs at a branch office by replacing regional MPLS through aggregate Internet links, SD-WAN at the edge does not optimize traffic over the middle mile.

For an SD-WAN to fully tackle those challenges on a global scale, it must leverage a private network that is layered over the Internet to accelerate data and application performance. In that way, the SD-WAN can replace MPLS by combining a private network in the middle mile and Internet at the edge, while still providing MPLS-grade connectivity in all geographies where business is conducted, delivered via privately owned and maintained points of presence (POPs).

As a global enterprise looking to maximize your investment, free up IT resources, and improve application performance throughout the whole network and not just at the edge, the best bet is to work with a global SD-WAN provider with a private WAN.

Aryaka’s global SD-WAN fits that bill: We are the only provider that provides an “in-net” solution that is actually an MPLS-grade global private network. Built on a foundation of 28 points of presence that are located within 30 ms of over 95% of the world’s business users, Aryaka’s network both software-defines a secure, private WAN and shortens the distance that data must travel, thereby minimizing latency. In addition, Aryaka’s network contains proprietary technology to nearly eliminates all packet loss.

This private WAN is also built for consumption. IT staff are given visibility and measurement tools in the built-in MyAryaka™ portal, but the burden of management is removed, because Aryaka is delivered as-a-service. We also provide 24×7 CCIE-level technical support for any concerns that might arise.

Aryaka’s global private network allows enterprises to be connected to both the data center and cloud or SaaS-based platforms and applications, eliminating the need for backhauling or hybridizing traffic. The network is multi-purpose and with built-in load balancing, WAN Optimization and acceleration, it increases throughput and improves performance.
