Multi-AZ AWS IoT agricultural monitoring architecture ingests sensor data from weather and soil gateways via IoT Core and MQTT, routing streams through Kinesis to Lambda processors for validation and anomaly detection. Data flows to RDS PostgreSQL with read replicas, Timestream for time-series metrics, and S3 archival, while SNS triggers alerts and CloudFront CDN serves the farm dashboard through API Gateway and Cognito authentication. This production-grade design demonstrates high availability across availability zones, secure credential management via Secrets Manager, and comprehensive monitoring with CloudWatch and CloudTrail for compliance.
