Minimizing Risk During SD-WAN Solution Deployment

The number of software-defined WAN (SD-WAN) deployments grew from virtually nothing at the start of the 2010s to approximately 4,000 by 2017, according to Gartner's estimates. Plus, there's no sign of a looming slowdown: An IDC forecast is expecting worldwide revenue from SD-WAN infrastructures and services to surpass $8 billion by 2021, after surging at a 69.6 percent compound annual growth rate between 2017 and then.

This broad, ongoing transformation of WAN connectivity is a response to the need for more up-to-date remote office, branch office (ROBO) strategies, as well as to particularly demanding application classes such as video, VoIP and various cloud-based services. That said, no one should rush into network modernization, despite the clear SD-WAN versus traditional WAN mismatch.

Pursuing a DIY approach, without a clear transition plan, can even result in less secure and unreliable WAN connectivity, which is why it's wise to thoroughly evaluate requirements, RBO sites and vendors before making a decision. Here's a checklist of what to do before giving your SD-WAN deployment the green light:

Carefully Assess Vendors

Gartner recently documented reductions in enterprise site per megabit monthly network services expenses across three major regions can result in savings due to SD-WAN adoption. In the U.S., Gartner saw organizations with savings of as much as 378 percent; in EMEA, 225 percent; and in APAC, 184 percent.

SD-WAN is not a commodity. Each provider has its own set of technologies affecting how the solution handles and secures traffic. For example, Talari Networks leverages a unique Quality of Experience (QoE) engine combining link, path and session layer intelligence. The QoE core conducts constant assessment of WAN connectivity conditions, with packets received every few microseconds and adjustments made without impact on end-users. Key security integrations with tools from partners like Zscaler and Palo Alto Networks also ensure safe connections to the cloud.

Get More Value from MPLS

Performing a rip and replace of existing WAN connectivity is not just disruptive, it's often costly, too. A better way forward is to find an SD-WAN platform that lets you preserve links such as MPLS and get more value from them through aggregation with other modes of transport like broadband and cellular. Being able to make the full aggregated bandwidth of the WAN accessible to all locations is great for both application performance and the bottom line, as you can save on MPLS upgrades and perhaps get better deals from service providers.

Find a Cost-Effective Road to ROBO Modernization

ROBO sites are often understaffed and forced to work with limited resources. Transforming them requires improvements in the availability of network bandwidth, not to mention simplification of security infrastructure. By integrating different link types along with a centralized controller that abstracts WAN connectivity from its underlying transport, ROBO strategy can be made more sustainable.
