Amazon SQS API
Amazon Simple Queue Service — a fully managed message queuing service for decoupling and scaling microservices, distributed systems, and serverless applications.
Best When
You're building on AWS and need reliable, scalable point-to-point message queuing with minimal operational overhead.
Avoid When
You need message streaming with replay, complex routing, or pub/sub to many consumers.
Use Cases
- • Decoupling microservices with async message passing
- • Buffering writes for downstream systems that can't keep up with bursts
- • Fan-out messaging when combined with SNS for multiple subscribers
- • Dead letter queue handling for failed message processing
- • Agent task queuing for distributed AI workflow execution
Not For
- • Real-time pub/sub with many consumers (use SNS or Kafka)
- • Message streaming with replay/rewind semantics (use Kinesis or Kafka)
- • Message ordering beyond FIFO queues
- • Sub-millisecond latency requirements
