The Challenge

They faced systemic limitations in their backend replication model and were unable to:

• Maintain data synchronization across ships with prolonged offline operations
• Resolve data conflicts between ship and shore systems without native tooling
• Manage operational risk from a replication platform nearing end-of-life
• Troubleshoot failures with limited visibility across distributed environments

The Objective

The goal was to modernize backend data replication without disrupting mission-critical ship and shore systems.

• Enable reliable bi-directional data synchronization under intermittent connectivity
• Preserve existing Relational Database and stored procedures
• Introduce intelligent conflict detection and resolution
• Provide centralized monitoring, observability, and reporting

The Solution

Bi-directional Replication: Implemented event-based replication with buffering and retry mechanisms to support intermittent ship connectivity

Conflict Resolution: Centralized logic to detect and resolve concurrent updates between ship and shore systems

Cloud-Agnostic Platform: Built on open-source tools, deployed via Kubernetes, retaining current relational database with CDC and no schema changes

The Impact

AntStack’s team established a clear path to improving ship-to-shore data reliability.

• Enabled reliable ship-to-shore data synchronization despite network outages
• Removed dependency on end-of-life replication tooling
• Preserved existing backend investments without database refactoring
• Improved operational visibility with centralized monitoring and reporting
• Reduced operational risk and future-proofed backend replication architecture
