AILANG toolchain multi-AZ architecture spans two AWS availability zones with CloudFront CDN, WAF, and dual ALBs routing traffic to EC2 compiler runtimes and ECS deterministic runners. Lambda example validators orchestrate inference calls to Anthropic, Gemini, and OpenAI endpoints while persisting CI results to RDS primary/standby and badge state to DynamoDB with cross-region replicas. This design ensures high availability, fault tolerance, and seamless AI model validation across geographically distributed infrastructure. Fork and customize this diagram on Diagrams.so to adapt the multi-AZ topology, add additional model endpoints, or modify database replication strategies for your toolchain requirements.
