Why do modern businesses need SD-WAN technology?

Are you facing troubles with your current network infrastructure? Probably it is time to consider the benefits of software-defined WAN solutions (SD-WAN). Today more and more organizations are moving from legacy technologies to SD-WAN ethernet and getting themselves ready for cloud computing.

Yes! This swift is majorly to become cloud-ready and enhance overall customer experience. You must have heard about WAN (wide area network) solutions, but SD-WAN might be a new term for you. If so, luckily, you are at the right place.

This article will discuss everything you need to know about the latest software-defined WAN Ethernet solutionand how they help companies improve their network performance for cloud-based resources.

What is SD-WAN?

SD-WAN is an automated, programmatic, software-based approach that helps you manage your enterprise network connectivity. It incorporates SDN (software-defined networking) into an application so that business can extend their enterprise networks over large geographical areas.

WAN utilizes multiprotocol label switching (MPLS), broadband, wireless, virtual private networks (VPNs), and the internet. It helps provide access to corporate applications, resources, and services to remote users to work efficiently regardless of their location.

While traditional WANs used to rely on physical routers to connect the users, each router has a data plane and a control plane to hold the data and direct the data respectively.

SD-WAN separates the control and management process and makes them available like a software application that can be easily configured and deployed. That said, the modern-day WAN solutions offer central manageability, ease of deployment, reduce costs, and improve connectivity and customer experience.

Why do businesses need SD-WAN?

WANs were introduced in an era that focused on linking physical locations. Hence, it leveraged the old approach to meet the modern needs of the businesses, resulting in expensive and cumbersome connectivity and complex topologies that were difficult to manage and secure. Over that, its unending cycle of patching, frequent updating, and upgrading required skilled professionals.

In contrast, the five reasons that are driving businesses to use SD-WANs are:


SD-WANs allow professionals to make the network changes efficiently at all locations as and when required that too via one platform simultaneously. Unlike traditional WANs, configuring new or existing infrastructure was a strenuous task, and there were chances that adjustments may not work adequately.


With traditional network solutions, users faced many issues like slow applications and unsecured connections. However, with SD-WANs, even the organizations such as healthcare, education, and construction, that need to connect branch offices can efficiently utilize SD-WAN technology and route large portions of their traffic cost-effectively.

With SD-WAN, any site can be connected quickly to any network, and even the links can be added for increased bandwidth and reliability.

Enhanced performance

This is the most critical advantage of SD-WANs because of which more and more companies are making the transition. You can easily configure your network according to your organization’s specific needs when using SD-WANs.

For example, it enables you to increase or decrease the bandwidth as per your business demand and improve performance where you need it the most. With SD-WANs, you enjoy speed and reliability, making a huge difference in your day-to-day life.                


With the chance to reap the benefits of improved performance, reliability, and security, you can also save a lot of money using a Software-defined WAN Ethernet solution.

Yes, you read it right! This modern-day technology keeps pace with your business while helping you reduce overhead and equipment spending. SD-WAN saves you money even when your business grows as it offers simple deployment and configuration.
