SD-WAN and traditional WAN are both used to connect networks over a wide area, but there are some key differences between the two.
Traditional WANs typically use dedicated hardware such as routers and leased lines to connect branch offices to a central network. They are often expensive and difficult to manage, and do not provide the flexibility to dynamically adapt to changing network conditions.
SD-WAN, on the other hand, uses software to manage and optimize network traffic, eliminating the need for dedicated hardware and making it easier to manage the network. It allows administrators to dynamically steer traffic over the best available network path based on real-time network conditions, providing improved network performance, security, and reliability.
In summary, SD-WAN is a more flexible, cost-effective, and easier to manage alternative to traditional WANs, particularly for organizations with multiple branch offices and a growing reliance on cloud and internet-based applications.
