Agentic workflow platform on AWS ECS Fargate orchestrates LLM-powered tasks using Temporal for durable execution. Public API pushes events to ElastiCache for Valkey (Redis Streams), triggering Temporal Workers that invoke Vertex AI or OpenAI models and persist state to Aurora PostgreSQL. This architecture enables reliable, observable AI agent workflows with automatic retries and long-running task management—critical for production LLM applications requiring fault tolerance. Fork this diagram on Diagrams.so to customize worker scaling policies, swap LLM providers, or add step function orchestration. CloudWatch integration provides full observability across Temporal Server and Worker containers.
