Global Network Transformation for a Travel Retail Enterprise

Global SD-WAN Architecture & Seamless Cloud Migration

Overview

A global travel retail enterprise needed to unify its international network and migrate core systems to the cloud, but faced unstable cross-border performance, inconsistent IT standards, and rising operational complexity.

ESUN designed a Fortinet SD-WAN global architecture with unified operations, helping the customer improve cross-border connectivity, reduce IT workload, and complete its cloud migration with stability and control.

Challenges

1

Inconsistent network performance across regions

The customer relied on a mix of MPLS, leased lines, and local Internet services, resulting in uneven connectivity quality.

2

High troubleshooting workload

Fragmented links and scattered operations made fault handling slow and difficult for IT teams.

3

Limited visibility for global operations

The lack of centralized management made it hard to standardize service quality across stores and offices.

4

Cloud migration risk

The planned migration to JD Cloud required stable connectivity to avoid disruption to business operations.

Solutions

  • Global SD-WAN architecture

    Built a secure global backbone using Fortinet SD-WAN over MPLS, linking Mainland China, Hong Kong, and Europe.

  • Unified operations model

    Standardized service management across regions with both on-site and remote support under one framework.

  • 7×24 monitoring with SLA response

    Provided round-the-clock monitoring and SLA-based incident response to reduce troubleshooting delays.

  • Hybrid-cloud connectivity enablement

    Enabled stable cloud and on-premise connectivity to support a smooth and fully controlled JD Cloud migration.
