SD-WAN provides enterprises a sustainable alternative to high latency hub-and-spoke network topologies.

FREMONT, CA: SD-WAN is a revolutionary method of routing traffic on the network, with several potential benefits for enterprises. SW-WAN enables routing changes to be made at the software level rather than directly at the router. This mitigates the costs of the routers and lets for much more flexibility and control. But is it right for the organization? How can organizations take advantage of it? Here's a guide to what it is, how it could benefit the business, and the major factors enterprises requiring considering before implementing it.

SD-WAN is the most capability in WAN that simplifies connectivity between the branch offices and remote locations. If the organization has a Wide Area Network, MPLS-based, software-defined networking potentials can be applied to it as a virtual overlay. Leveraging an SD-WAN architecture, firms can connect the data centers and branches and accelerate the network's performance for less than it would cost to use MPLS alone. Firms can also configure SD-WAN onto the infrastructure rapidly and seamlessly, which can lead to big savings.

One of the significant advantages hereof SD-WAN is the efficiencies in the speed of implementation. Operations that conventionally need extensive hardware and lengthy lead times can now be spun up, deployed, and business-ready in few days. The advantages also extend past the efficiencies in time and cost. SD-WAN allows several WAN links to enable QoS, whereas conventional WAN offers customers a single link. The scalability of this has seen a rise across verticals from education to retail. Large and small firms have much to gain from SD-WAN as file sizes evolve and traffic from the IoT devices increases. Robust, QoS can keep the essential traffic from flowing smoothly across their networks, and addressing such problems is quicker and more seamless with SD-WAN.

Secure web gateways can monitor traffic from remote users, even through SD-WAN connections. This protection is usually facilitated by endpoint agents deployed on mobile and branch office user machines, which triggers routing through secure web gateway cloud infrastructure for filtering that works even on distributed networks. Additionally, secure web gateways usually centralize visibility across all users and devices into a single dashboard. In most cases, this can be coupled into a broader security portfolio that comprises other conventional inspection technology.
