Multi-cloud financial trading platform spanning AWS, GCP, and on-premise infrastructure orchestrates order matching, risk analysis, and regulatory compliance across distributed systems. AWS hosts the primary trading engine with EKS clusters running order matching, position management, and trade execution services backed by ElastiCache Redis for microsecond latency and Aurora PostgreSQL for transactional consistency. GCP provides analytics and ML capabilities through GKE Autopilot clusters running fraud detection and portfolio optimization services with Vertex AI model serving and BigQuery for real-time market analysis. On-premise data center maintains regulatory reporting and audit trail services connecting legacy Oracle systems through HashiCorp Vault for secrets management and Confluent Schema Registry for event schema governance.
