AWS SQS
Amazon Simple Queue Service, a fully managed message queuing service provided by AWS. It supports error-handling mechanisms such as dead-letter queues (DLQ) and is used to decouple distributed system components while enabling reliable asynchronous message delivery.

Having cron directly execute the full Agent logic (such as */15 * * * * node run-agent.js) is a bad pattern; the standard pattern is for cron only to enqueue (such as node enqueue-agent-job.js, writing to BullMQ, SQS, or Cloudflare Queues), with a separate worker executing the Agent steps.
The criterion for choosing queue tooling is that the team can still operate it correctly at a 2 a.m. outage: BullMQ suits Node.js workers, Temporal suits multi-step orchestration with long waits and approvals, AWS SQS suits AWS-native managed queues, and Cloudflare Queues suits edge-friendly batch-processing architectures.
Common dead-letter queue implementations include Apache Kafka's dedicated Topics, AWS SQS's Dead Letter Queue configuration, and RabbitMQ's dead-letter exchange.
AWS SQS提供标准队列（至少一次投递，可能乱序）和FIFO队列（精确一次投递，严格有序）两种模式
AWS SQS采用至少一次投递语义，消息可能被重复消费
