4 Instances That Demand An SD-WAN Solution


In today’s enterprise world, technology is king. While the growing number of platforms and systems included in a business’s infrastructure enables new capabilities and helps boost productivity, these tools also create an increasingly complex network that requires more granular oversight.

This is where an SD-WAN comes into play – but it isn’t the only time your company should look to such a solution.

Overall, the SD-WAN market is exploding as more companies in every vertical implement these tools. According to Current Analysis Research Director Mike Fratto, SD-WAN is the new WAN optimization, and is seeing the same kind of skyrocketing demand. A study from Kable Global ICT Customer Insight found that of the 2,600 survey participants, more than 58 percent are planning to deploy an SD-WAN solution within their enterprise network in the next two years.

Those that have adopted the technology have quickly realized the vast benefits that these solutions can offer. At the same time, companies without SD-WAN are discovering a number of instances that increasingly require the advanced capabilities that this technology can provide. Let’s take a look at the top four occasions that demand SD-WAN:

1) When the legacy WAN is no longer good enough

Before we get into more detailed instances, it’s important to look at the big picture. In addition to increasingly complex infrastructure, the traditional WAN in many businesses simply can’t offer the level of performance and quality experience that is required in the current corporate landscape.

“The traditional WAN in place in many businesses simply can’t offer the level of performance and quality experience that is required.”

Companies across every industry need a failsafe network that provides round-the-clock support for critical applications, even in the face of common WAN issues like packet loss and latency. The WAN represents a critical resource for staff members, but if it isn’t providing the top-notch performance employees need, the organization could fall behind its competitors in the marketplace.

“With all the money that you invest in your business’s wide area network, you expect a certain ROI,” Talari Networks pointed out in our recent white paper, “10 Tips for Building a Failsafe Network.” “However, if your users are experiencing problems like poor application performance or downtime, your network could be leaving you needing more.”

If this is the case within your business, it’s time to update your legacy WAN with an SD-WAN solution that can provide the type of performance and support you require.

2) When connectivity costs are out of control

No matter what industry an organization operates within, the budget is a constant priority for the executive team as well as IT managers. However, as technology budgets continue to shrink, companies need to ensure that costs are under control and that resources are being used in the best ways possible.

An SD-WAN can help your company achieve both of these goals, thanks to the technology’s ability to leverage cost-effective connectivity links. Many businesses have found that they’re able to cap their investment in expensive MPLS links and add capacity using more affordable broadband internet.

What’s more, SD-WAN technology can also ensure that all WAN links are utilized to support the very best network performance. As opposed to having links in place solely for backup, an SD-WAN leverages all connections to appropriately route data traffic. This ensures that businesses see the highest return on investment when it comes to their connectivity.

3) When critical applications aren’t performing as they should

It’s happened to everyone at least once – you’re on a VoIP call with a manager, business partner or other important corporate contact when the sound delays and everyone is talking over one another. Worse still, lackluster performance can also result in dropped calls, thereby preventing communication, collaboration and productivity.

Critical applications form the backbone for many of the most important enterprise processes, and require failsafe network support.

With an SD-WAN, these types of issues can be completely eliminated – and not just for VoIP calling, but all mission-critical applications. SD-WAN technology allows the company to create unique policies for data traffic routing, ensuring that packets associated with the most essential network activity are effectively prioritized. This, combined with the technology’s ability to measure packet loss, latency, jitter and availability of every network link allows it to work proactively to avoid any problematic WAN connections. The bottom line here is that data traffic takes the best path, every time, providing the highest-quality user experience possible.

4) When outages are unacceptable

In the past, service outages that prevent access to key applications were simply something businesses dealt with. If an outage occurred, productivity was lost, but there was little the company could do.

Now, all that has changed thanks to SD-WAN. This solution can help create a failsafe network where WAN support is in place even if a service provider experiences downtime.
