The Shift to SD-WAN
For years, MPLS was the default for enterprise WANs: reliable, predictable, and expensive. Over the past decade SD-WAN has gone from niche to mainstream, and plenty of businesses now run the two side by side or drop MPLS entirely.
Why the Change?
A few things are pushing the change:
**Cloud Application Growth** — With businesses relying on SaaS applications like Microsoft 365, Salesforce, and cloud-hosted ERP systems, the traditional hub-and-spoke WAN architecture creates unnecessary latency by backhauling cloud traffic through centralized data centers.
**Cost Pressure** — MPLS circuits are expensive, and bandwidth demands continue to grow. SD-WAN lets you run cheaper broadband links and stay reliable by steering traffic across multiple paths and failing over when one degrades.
**Agility Requirements** — Modern businesses need to spin up new locations quickly. SD-WAN solutions can be deployed in days rather than the weeks or months required for traditional WAN circuits.
Key Benefits
Improved Application Performance — Intelligent traffic steering ensures critical applications always use the best available path.
Cost Reduction — Typical savings of 30-50% compared to equivalent MPLS bandwidth.
Simplified Management — Centralized orchestration and zero-touch provisioning cut the manual work of standing up new sites.
Enhanced Security — Built-in encryption and integration with cloud security services.
Making the Transition
The move to SD-WAN doesn't have to be all-or-nothing. Many organizations adopt a hybrid approach, maintaining MPLS for their most critical circuits while adding broadband-based SD-WAN for additional bandwidth and new locations.
