Software-defined wide area networks (SD-WANs) have many benefits, but their key advantages are improving the user experience, leveraging WANs more efficiently, reducing costs and simplifying operations. Proper planning and design of an SD-WAN deployment makes for a smoother process while minimizing potential issues.
Optimizing an SD-WAN deployment, particularly a large-scale one, requires a structured methodology. It’s critical to spend time in the beginning on a thorough requirement-gathering process, which can reduce the number of issues that arise during deployment. Rigorous planning allows for better design, which in turn supports the development of templates that speed up deployment, reduce mistakes and take advantage of economies of scale.
