Amazon SQS
Fully managed message queuing for decoupling microservices — Standard queues for throughput, FIFO for strict ordering, dead-letter queues for automatic failed-message handling. Most-used open-source equivalent is RabbitMQ (direct queueing analogue, DLQ support built in); NATS JetStream is a common lighter-weight alternative for teams already on NATS for pub/sub.
