About This Architecture

Enterprise trading platform architecture spanning Cloudflare edge protection, AWS CloudFront CDN, and a multi-tier EKS cluster across two availability zones with segregated namespaces for always-on, elastic, and critical workloads. Data flows from Traders and Admin web clients through Cloudflare WAF and DDoS protection into Route 53 and CloudFront, then to an Application Load Balancer routing traffic to EKS pods running Auth, User, KYC, Risk Engine, and Trading Data Sync services. PostgreSQL RDS with read replicas, ElastiCache Redis, and MSK Kafka provide persistent state, caching, and event streaming, while Istio service mesh, Karpenter autoscaling, and HPA manage resilience and cost. This architecture demonstrates multi-layer security (AWS WAF, Shield Advanced, GuardDuty, KMS), observability (Datadog, CloudWatch, X-Ray), and compliance (Secrets Manager, IAM/IRSA, CloudTrail) essential for regulated financial platforms. Fork this diagram on Diagrams.so to customize namespaces, add additional AZs, or integrate your own monitoring stack. Consider adding VPC Flow Logs and additional GuardDuty detections for enhanced threat detection in production trading environments.
