1. Managed Messaging: No need to manage and scale your own messaging infrastructure.

2. Scalability: Automatically handles increasing or decreasing message throughput based on demand.

3. Reliability: Provides durable message storage with redundancy across multiple Availability Zones.

4. Security: Supports encryption for message data at rest and in transit.

5. Flexibility: Allows messages to be processed by multiple consumers independently.

6. Two Queue Types:

   • Standard Queue: Offers unlimited throughput with at-least-once message delivery and best-effort ordering.

   • FIFO Queue: Guarantees exactly-once message processing and message ordering for strict sequential workflows.
