SD-WAN: What it is and why businesses need it

The broadband speeds that we take for granted today were a game-changer when they first became widely available. For businesses, this meant being able to connect to the internet constantly, without having to worry about downtime. This was a major benefit, as it allowed businesses to remain connected and productive even when there were problems with their primary internet connection. However, as business demands grew and more employees began working remotely, the need for faster and more reliable internet connections became apparent. This is where SD-WAN comes in. SD-WAN is a type of broadband that can provide the high speeds and reliability that businesses need to stay productive, even when their primary internet connection is down.

What is SD-WAN?

Before we dive into the topic, let us first understand what Wide Area Networks (WAN) is ─ A wide area network (WAN) is a large computer network that extends over a large geographic area. Devices that are connected to a WAN can communicate with each other regardless of their location. When businesses globalize, WAN helps them to share data between branches and stay connected.

SD-WAN is a software-defined approach to wide-area networking that enables enterprises to manage network connectivity and circuit costs in an automated and programmatic way. SD-WAN enables enterprises to connect their branch offices and data centers using any combination of transport technologies, including MPLS, Ethernet, and Internet. It provides a single platform for managing all aspects of enterprise network connectivity, including performance, security, and cost. It works by creating a network of SD-WAN appliances connected by encrypted tunnels. Each site on the WAN has its own SD-WAN appliance, and all traffic flows through that appliance. The SD-WAN appliance uses algorithms to determine the best route for each packet of data, and then sends it on its way. This results in improved performance and reduced latency, as well as increased security and resilience.


When it comes to choosing a Wide Area Network (WAN) solution, there are two main options: MPLS and SD-WAN. Both have their pros and cons, but SD-WAN is increasingly becoming the preferred choice for many businesses. Compared to MPLS, SD-WAN can be less expensive, more secure, and provide higher performance. One of the biggest advantages of SD-WAN is that it uses multiple transport technologies, which makes it more resilient than MPLS. Additionally, SD-WAN can be easily deployed and managed remotely, which further reduces costs.

Why businesses should invest in SD-WAN-

There are several reasons why businesses should consider investing in SD-WAN technology. One of the most important benefits is the increased flexibility and agility it offers. With SD-WAN, businesses can easily connect to multiple cloud providers and quickly scale their network up or down as needed. Additionally, SD-WAN can help improve application performance and reduce latency. It can also provide better security and allow businesses to centrally manage their network. While there is an upfront cost to investing in SD-WAN, the long-term benefits outweigh the short-term costs. Any business that wants to stay ahead of the curve should invest in SD-WAN technology. It provides a centralized portal to control and manage all areas of network performance through the cloud. This means that businesses can optimize their networks for specific applications, ensure Quality of Service (QoS), and reduce costs. It also offers increased security and reliability, making it the perfect toolkit for businesses of all sizes.
