Global Flight Data Exchange using Solace Event Mesh integrates multi-region brokers across US-East, EU-West, APAC, and ME with AWS services including ECS, Lambda, MSK Kafka, RDS Aurora, and DynamoDB. Publishers like airlines, airports, booking agents, and crew systems connect via Solace PubSub+ to internal subscribers including Order Service, Flight Events Lambda, Booking Service, and Crew Events Lambda across two availability zones. The architecture decouples external partners from internal systems through event-driven patterns, enabling real-time flight data synchronization while maintaining security boundaries via VPC isolation, WAF, and IAM. Fork this diagram on Diagrams.so to customize broker regions, add additional Lambda functions, or adjust subnet CIDR blocks for your flight operations platform. Consider adding Solace message VPN segmentation for multi-tenant isolation if supporting competing airlines on shared infrastructure.
