You’ve probably heard the word SD-WAN before. But do you have an idea what it actually means? SD-WAN or software defined wide area network is a virtual WAN architecture that lets businesses use a mix of transport services like broadband internet services, LTE, or MPLS to connect users to certain applications securely.
SD-WAN makes use of a centralized control function to intelligently and securely direct traffic across the wide area network. This will boost the performance of the application and provide top notch user experience, which can result into improved agility, business productivity, as well as lower IT costs.
Traditional wide area network that were based on the conventional routers weren’t made for the cloud. They generally need to backhaul all traffic like the cloud destined traffic, from a branch office to a headquarters data center or a hub where complex security inspection solutions can be applied. The delay that’s caused by backhaul will impair application performance, which leads to lost productivity and poor user experience.
Compared to the conventional router-centric WAN architecture, an SD-WAN Columbia SC model is made for applications that are hosted in an on-premise data center, private or public clouds, as well as SaaS solutions like Dropbox, Office 365, Workday, and Salesforce.com, while providing top quality application performance.
Understanding How SD-WAN Works
Cloud first enterprises can provide top quality application quality of experience for its users using an SD-WAN. By identifying applications and through intelligence, SD-WAN Columbia SC offers application aware routine throughout the wide area network. Every type of application gets the right QoS as well as security policy enforcement, based on the business needs.
Top quality cloud performance is provided thanks to the secure local internet breakout of SaaS and IaaS application traffic from their branch while securing the business from threats. Compared to an SD-WAN, a traditional router-centric model provides the control function on all devices within the network and just routes traffic according to the TCP/IP addresses ACLs. However, this model is typically inefficient, rigid, and not cloud-friendly, which leads to a poor user experience.
