Overview
Our team collaborated with a global travel and transportation leader to develop an enterprise messaging system for seamless subsystem integration across international airports. This high-availability solution was designed to meet critical requirements, ensuring zero downtime, enhanced message routing, role-based access, and secure data handling to support mission-critical airport operations.
Challenges
The system required continuous uptime to avoid disruptions in flight operations, making high availability essential. Multiple subsystems with distinct needs necessitated role-based access controls and custom user interfaces. Efficient routing was required for complex message processing, and integration with external subsystems demanded adaptable connectors. Additionally, robust system administration and stringent data security were imperative to maintain operational reliability and compliance.
Solution
We implemented a modular microservices architecture with an active-active-standby setup for high availability, supported by a load balancer and real-time resource monitoring. A dedicated routing module processes messages with transformations, encryption, and notifications for external systems, ensuring accurate and timely delivery. Role-based access control (RBAC) and an administrative user interface offer flexibility for managing users, monitoring subsystems, and configuring message processing. Additionally, a connector-based architecture with an Adapter Development Kit (ADK) facilitates seamless integration with external subsystems.
