What is Managed SD-WAN?

SD-WAN (a software-defined wide area network) is defined as a virtual WAN architecture, in which the control of network connections, application flows, policies, security mechanisms and general administration is separated from the underlying hardware. Everything is managed in software on centralized consoles instead of at the physical locations of individual edge devices and infrastructures.

How does SD-WAN work?

An SD-WAN connects end users to virtually any application, hosted at any location (e.g., in the public cloud or a company data center), via the best available or most feasible transport service, whether that’s an MPLS (Multiprotocol Label Switching), broadband, cellular or even satellite internet link. To deliver this level of flexibility and performance to users in digital workspaces, an SD-WAN utilizes a control function that continuously analyzes traffic flows across the WAN and intelligently directs traffic in accordance with current policies.

Why do businesses need SD-WAN

Traditional WANs based on conventional routers are not cloud-friendly. They typically require backhauling all traffic – including that destined to the cloud – from branch offices to a hub or headquarters data center where advanced security inspection services can be applied. The delay caused by backhaul impairs application performance resulting in a poor user experience and lost productivity. Unlike the traditional router-centric WAN architecture, the SD-WAN model is designed to fully support applications hosted in on-premise data centers, public or private clouds and SaaS solutions such as Salesfore.com, Workday, Office365 and Dropbox, while delivering the highest levels of application performance.
