Modern AI systems are evolving from single prompts into networks of collaborating agents that plan, delegate tasks, invoke tools, and coordinate actions across distributed systems. But orchestrating multiple agents introduces the same architectural challenges you've faced with microservices: shared state, retries, partial failures, consistency, and long-running workflows. In this session, we explore patterns for building durable multi-agent systems. We'll examine orchestration vs. choreography, agent coordination models, workflow durability, and failure handling, and show how Lambda Durable Functions implement them. You'll leave with practical frameworks for designing reliable, observable multi-agent architectures on AWS.
