Hi All,
I would like to understand your opinion about SD-WAN- A Software-defined Wide Area Network (SD-WAN).
Do you see it as something that management or IT strongly believes in? How would you spot the management or board of directors who just want to safety-wash?Thanks,
Chuck
A Software-defined Wide Area Network (SD-WAN) is a virtual WAN architecture that allows enterprises to leverage any combination of transport services – including MPLS, LTE, and broadband internet services – to securely connect users to applications.
An SD-WAN uses a centralized control function to securely and intelligently direct traffic across the WAN. This increases application performance and delivers a high-quality user experience, resulting in increased business productivity, agility, and reduced costs for IT.
Traditional WANs based on conventional routers were never designed for the cloud. They typically require backhauling all traffic – including cloud- destined traffic – 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 services such as Salesforce.com, Workday, Office 365 and Dropbox, while delivering the highest levels of application performance.
