SD-WAN for Small Businesses

Software-defined wide area networking (SD-WAN) separates network control from hardware. Instead of routing all traffic through a single MPLS circuit or internet connection, SD-WAN dynamically chooses the best path for each application.

Why small businesses consider SD-WAN:

- Combine multiple connections (fiber, cable, cellular) for redundancy.

- Prioritize business-critical traffic like VoIP and video over less critical traffic.

- Fail over automatically if one connection goes down.

- Manage branch and remote site networks from a central dashboard.

Trade-offs to consider:

- SD-WAN adds appliances or software at each site.

- You still need underlying internet connections — SD-WAN manages them, it does not replace them.

- Configuration complexity is higher than a simple router setup.

SD-WAN fits businesses with multiple locations, remote workers, or applications sensitive to downtime. A single-office business with one internet connection may not see enough benefit to justify it.
