Case Study: Logistics & TMS SaaS Company achieves resilient AWS migration and multi‑ISP VPN failover with Cohesive Networks

Logistics & TMS SaaS Company - Customer Case Study

Logistics & TMS SaaS Company engaged Cohesive Networks to modernize and migrate a six‑server stack to AWS while maintaining connectivity to existing and updated IP addresses. The customer needed to link two discrete ISP carriers into a single VPN spanning AWS regions and ensure resilient IPsec connectivity during and after the move.

Cohesive Networks deployed two VNS3 Controllers—starting with VNS3:Lite for a proof of concept and, after a few weeks of testing and support, upgrading to VNS3 SME Edition—to provide reliable failover between IPsec tunnels across both ISPs and AWS regions. The result was a successful migration to AWS with multi‑ISP VPN resiliency, expanded tunnel capacity, and removal of single‑carrier risk, enabling stable cloud operations.
