- SQS Standard queues offer high throughput with at-least-once delivery, while FIFO queues guarantee order and exactly-once processing.

- SNS is a publish/subscribe service that pushes notifications to multiple subscribers like SQS queues, Lambda functions, or email endpoints.

- SQS and SNS are fundamental services for creating decoupled architectures, which enhances application scalability and resilience.

- The fan-out pattern uses a single SNS topic to distribute a message to multiple SQS queues, enabling parallel and independent processing.

- A key exam distinction is that SQS consumers pull messages from a queue, whereas SNS pushes messages to its subscribers.
