If your network systems administrators stay ahead of the latest developments in network security, then you’ve probably already come across SD-WAN. Unlike traditional network environments, where traffic is based around a centralized point of control, routing, and security, software-defined wide-area networking (SD-WAN) breaks down centralized barriers to facilitate flexibility and responsiveness.
Traditional network environments have become increasingly vulnerable as operations migrate to the cloud and more users depend on outside internet connections to connect to work platforms. For many businesses, centralized network control no longer makes as much sense as it once did. That’s where SD-WAN comes into play. By routing the network based on users, roles, and rules, your network remains secure no matter where traffic is coming from or where it’s going.
SD-WAN also opens up new possibilities for network optimization by routing network traffic to the most efficient data center or server for a given operation. For example, if a member of your team is working remotely while connected to the Office 365 environment, their network traffic is automatically routed to the closest hosted data center to maximize performance.
At the same time, SD-WAN streamlines network management because it’s much simpler to modify network rules and roles as your organization’s needs evolve over time. That means an SD-WAN network generally requires less overhead to operate while still opening up new possibilities for day-to-day network operations.
