Real-time milk powder lead generation system on AWS combines Route 53, CloudFront, WAF, and Shield Advanced at the edge with a multi-tier VPC architecture spanning presentation, application, streaming, data, ML, and security layers. Web and mobile users flow through ALB and API Gateway into ECS Fargate microservices for tracking, lead capture, and consent management, while Kinesis Data Streams and MSK Kafka bus real-time intent events to Lambda classifiers and scoring engines. Aurora PostgreSQL, DynamoDB, ElastiCache, and S3 data lake (Bronze/Silver/Gold) feed SageMaker model training and Bedrock LLM for next-best-action recommendations, with results streamed to an ECS Fargate real-time dashboard via AppSync GraphQL subscriptions. This architecture demonstrates secure, scalable event-driven lead scoring with built-in encryption (KMS), audit logging (CloudTrail), threat detection (GuardDuty), and multi-layer DDoS protection for high-velocity B2B lead capture.
