Multi-AZ AI contract analysis platform leveraging AWS CloudFront, WAF, ALB, FastAPI backends, and RDS with DynamoDB for intelligent document processing across us-east-1a and us-east-1b. User requests flow through CloudFront CDN and WAF protection to Application Load Balancers, routing to FastAPI servers that orchestrate PDF/DOCX/TXT file processing, clause extraction, risk analysis, and obligation detection via Gemini, Claude, or GPT-4 APIs. RDS Primary in AZ-1 replicates to RDS Standby in AZ-2, while DynamoDB Analysis Results sync across availability zones for zero-downtime failover and sub-millisecond query performance. This architecture demonstrates enterprise-grade security, high availability, and scalable AI inference for contract intelligence workloads. Fork and customize this diagram on Diagrams.so to adapt database instance types, add Lambda for async processing, or integrate additional LLM providers. Consider adding S3 for contract document storage and CloudWatch for observability across both AZs.
