AWS SQS
This lesson is part of AWS · All levels
Summary
Amazon Simple Queue Service (SQS) is a managed queue service for hosting and moving messages between application components. SQS provides standard queues that guarantee a minimum one-time delivery, as well as FIFO queues that maintain order and avoid duplicates. With long polling and visibility timeout, consumers can process messages efficiently without flooding the system.
Key points
- Standard queue: at-least-once delivery, order not guaranteed
- FIFO queue: keep the order and prevent duplication of messages
- Visibility timeout hides messages while they're being processed
- Long polling reduces the demand and costs of empty
