Infrastructure Patterns for Agentic Applications
11 hours ago
- Agents need decoupling from HTTP requests due to being long-running, stateful, and non-deterministic.
- The Web-Queue-Worker pattern separates request from execution, but queues alone don't manage multi-step processes.
- Reliability requires idempotency for safe retries and compensation (saga pattern) for partial failures.
- Workflow engines provide orchestration, preserving run history and enabling replay determinism.
- Fan-out/fan-in enables parallelism but requires contention management and explicit failure policies.
- Platforms like Render Workflows simplify the execution plane, but application code must still handle semantic correctness.
