Geographically distributed enterprises are embracing Software-Defined Wide Area Networks (SD-WANs) at an accelerating pace. Why? Because SD-WANs not only dramatically lower costs, they help businesses become more agile by enhancing business productivity.
As applications continue to move to the cloud, networking professionals are quickly realizing that traditional WANs were never architected for a dynamic, internet-based environment. Backhauling traffic from the branch to headquarters to the internet and back again doesn’t make sense. Employees sometimes even find their business apps run faster at home or on their mobile devices than at the office.
So why aren’t more internet connections used for enterprise WAN services? Simple. Historically, the internet was a best-effort amalgam of networks. It wasn’t secure or reliable enough to meet business needs. And it certainly didn’t perform well enough to support latency-sensitive or bandwidth-intensive business applications.
With internet access redefining the economics of networking, the time is now to revisit the value of deploying broadband in the WAN. That is, as long as concerns over performance, reliability and security can be overcome.
So how do you harden a broadband internet connection to create a secure SD-WAN? How do you address the latency and performance limitations of broadband? How do you make sure that streaming cat videos don’t override the priority for business-critical applications? And if a business has hundreds or even thousands of branch offices, how do you make it simple to configure, manage and expand?

Moving to an SD-WAN
Non-Disruptive Migration is Possible
Adding SD-WAN to an existing WAN infrastructure couldn’t be simpler. With Silver Peak, it can be a seamless transition. During the migration, all existing WAN equipment, services and connections continue to operate as before. While it’s possible for EdgeConnect to replace existing WAN infrastructure, creating a virtual WAN overlay doesn’t require a forklift upgrade of existing routers or infrastructure at branch locations.
The virtual overlay also enables you to mix and match carriers by access technology and by geography, centralizing the management and administration of the entire WAN.
Our Partner tool’s flexible deployment model allows IT to add EdgeConnect appliances, either physical or virtual, whenever and wherever new sites are added to the SD-WAN. Once authenticated and authorized, Orchestrator automatically configures and seamlessly merges them into the SD-WAN.
In other words, you can start immediately and migrate at your own pace, without disruption.
