SD-WAN Explained in Plain English

Think of your network like a highway. There will always be cars trying to get on and off the highway at different points. Sometimes there are traffic jams, which can slow everyone down. And sometimes, there are accidents which can block the highway entirely.

Now imagine that you could route traffic around all of those issues. That’s what SD-WAN does for your network. It’s a software-defined system that gives you more control over how traffic is routed, so you can avoid problems and keep things moving smoothly. In this post, we’ll explain SD-WAN in plain English so you can see how it can benefit your business.

Define SD-WAN and its purpose

Software-Defined Wide Area Network (SD-WAN) is a type of WAN technology that uses software to automate routing and configuring network traffic across multiple locations. It allows efficient redistribution of bandwidth between sites according to application needs and policy requirements. For operations that rely on a large network spread over a wide geographic area, SD-WAN can reduce the cost and complexity involved in managing the network by allowing centralized control of all nodes. Moreover, businesses can connect their networks securely with greater flexibility and, when compared to traditional WANs or MPLS networks, improved performance, scalability and security. In short, SD-WAN provides enterprises with direct control over routing data across their network to optimize performance for critical applications and create high-performing multi-location IT infrastructures.

Give a brief history of SD-WAN development

Software-Defined Wide Area Network (SD-WAN) has been a recent development in the realm of networking technology. The concept combines software-defined networking principles with wide-area networking to enable organizations to deploy centralized control and policy management across their networks. This technology allows organizations to scale quickly, easily, and cost-effectively since the deployment is conducted over a virtual infrastructure. It also reduces resource usage compared to traditional hardware-based networks. It was first introduced in 2014 by VMware when it acquired VeloCloud and subsequently launched its SD-WAN solution that same year. Since then, the adoption of SD-WAN has grown significantly as organizations are taking advantage of its cost savings, scalability and reliability.

Explain how SD-WAN works

SD-WAN, or Software-Defined Wide Area Networking, is an innovative technology that allows for secure and manageable network connections over long distances. It works by merging the power of traditional WAN protocols, such as Multi-Protocol Label Switching (MPLS), with cloud-hosted management that leverages secure software components to align policy with enterprise objectives. This gives businesses many desirable features, such as increased bandwidth and reduced latency. The SD-WAN also offers improved security through firewalling and authentication capabilities while ensuring compliance at all levels of the organization. In a nutshell, SD-WAN provides businesses with a comprehensive solution for establishing secure and reliable wide-area networks.

Describe the benefits of using SD-WAN

SD-WAN, or Software-defined WAN, is an increasingly popular technology helping organizations access multiple types of traffic, including VoIP and video streaming services. By using SD-WAN, companies can more easily provision and manage their networks from a centralized virtual hub. This gives flexibility and control over the network that would not be available with traditional options. In addition, it enables companies to save costs on expensive hardware and time by providing dynamic paths for data routing, which eliminates manual interaction allowing IT teams to focus on other mission-critical tasks. Perhaps most importantly, SD-WAN offers significant performance enhancements in application response times and cloud deployments with greater reliability than traditional WAN solutions. Overall, SD-WAN is an excellent solution for staying ahead of the competition regarding modernizing networks and increasing secure connectivity across widely distributed sites.

Offer tips for choosing the right SD-WAN solution for your business

Choosing the right SD-WAN solution is a critical decision for any business, as it can be the difference between smooth and efficient networking operations or costly problems down the road. When selecting an SD-WAN solution, it is important to ensure that it meets your specific needs, considering factors such as application performance and scalability. Furthermore, you should look for an offering that offers the key features necessary for security and reliability, such as built-in redundancy, load-balancing capabilities and quality of service protocols. Additionally, researching potential vendors to confirm their customer support system helps provide convenient answers to questions you may have in the future. Ultimately, evaluating each aspect of an SD-WAN solution thoroughly with your own individual requirements in mind is essential before committing to a particular option.

Summarize the key takeaways about SD-WAN

SD-WAN is an effective and cost-efficient network technology that is becoming increasingly popular. It provides businesses with cloud connectivity, application performance optimization and simplified IT infrastructure management, which can bring many benefits. It is flexible, making it well-suited to companies with multiple sites or rapidly changing communications needs. SD-WAN also offers improved security as it allows IT managers, to monitor and track each data packet in the network, among other features. By eliminating dedicated circuit requirements, companies can save on costs while taking advantage of the advanced features available through SD-WAN solutions. To ensure a seamless integration that meets your specific business objectives and budget, thorough due diligence should be conducted before committing to an SD-WAN solution.


In conclusion, SD-WAN is a software-defined networking solution that offers many benefits for businesses, including increased security, improved performance, and reduced costs. When choosing an SD-WAN solution for your business, it is important to consider your specific needs and requirements. With the right SD-WAN solution in place, you can enjoy all the benefits that this cutting-edge technology has to offer.
