The Problem: Expensive MPLS with No Real Redundancy
A Dominican manufacturing company with headquarters in Santo Domingo and 4 plants in Santiago, La Romana, San Pedro de Macorís, and La Vega had a private MPLS WAN infrastructure costing $18,000 monthly. Each location depended on a single link — if it fell, that plant disconnected completely from the central ERP and operations came to a halt.
The Proposal: SD-WAN with Dual Heterogeneous Links
We proposed replacing the monolithic MPLS with a UniFi-based SD-WAN architecture using two connection types at each site: local fiber from the most economical ISP available in each area + 4G LTE as a secondary contingency link.
The Technical Solution: UniFi Dream Machine Pro router at each site with SD-WAN configured for automatic failover. The router monitors both links in real time with 5-second keepalives. If the fiber link fails, traffic migrates to LTE in under 3 seconds without interrupting active VoIP or ERP sessions.
Measured Results
- Monthly WAN cost: From $18,000 to $6,200 (including fiber + LTE at all sites). Savings: $141,600 annually.
- WAN availability: From 99.1% (single MPLS link) to 99.97% (fiber + LTE with automatic failover).
- Project ROI: Positive from the first month. Hardware paid for in 45 days of savings.
