What Are the Main Drivers of SD-WAN Adoption?

Last year, technologist Robert Cringely argued that the cloud computing tipping point was near, with the commercial and technical dominance of on-demand infrastructure all but inevitable within the end of the decade. This isn't a novel or even surprising claim, but his argument added some useful context by comparing the influence of cloud to previous watershed moments in computing, including the rise of graphical user interfaces and the mainstreaming of mobile devices.

However, if you had to determine whether this momentous occasion was indeed imminent based on nothing but observations about most WANs, you might conclude it was still far off. Traditional WAN implementations are as ill-suited to the cloud era as floppy disks were to the age of full-motion video games, yet they persist; only in 2017 did Gartner declare that rival software-defined WAN (SD-WAN) solutions had entered the mainstream and out-year projections of 50 or more SD-WAN replacing legacy WANs.

Switching to SD-WAN: A New Year's Resolution You Can Live by in 2018

On the bright side, there are better reasons than ever to switch to SD-WAN in 2018 and beyond, as long as you have the right SD-WAN provider lined up. IDC recently surveyed potential SD-WAN adopters to see what was forcing their hands on network upgrades. It found that the top four identified reasons for considering SD-WAN were:

  • Bandwidth optimization (cited by 36 percent of respondents).
  • Consistent application security (31 percent).
  • Integration with existing WANs (28 percent).
  • Automation and self-provisioning (also 28 percent).

Let's look at how SD-WAN addresses each of these goals:

Bandwidth

An SD-WAN solution enables full aggregated bandwidth access to real-time apps such as VoIP and video. It also allows liquid application flows even when jitter, packet loss and link failure are affecting the network.

Security

SD-WAN providers like Talari Networks support many security integrations and features for protecting traffic. For example, combining your SD-WAN with Zscaler ensures safe connections to cloud-based services.

Integration

Even if your current WAN includes a considerable MPLS investment, you don't have to rip and replace it just for the sake of SD-WAN. Instead, SD-WAN can augment your existing infrastructure by making it more cost-effective and easier to manage.

Automation

SD-WAN automatically and constantly measures paths for quality and seamlessly sends the most important traffic down the highest quality links available at a given time. Talari makes network evolution easy: Learn more by setting up a demo or clicking below.
