Amazon Simple Queue Service ( Amazon SQS) offers a secure, durable, and available hosted Queue thatlets you integrate and decouple distributed software systems and components. Amazon SQS offerscommon constructs such as dead-letter queues (p.)

9 86) and cost allocation tags (p. 84). It providesa generic web services API and it can be accessed by any programming language that the AWS SQS supports both standard (p. 70) and FIFO queues (p. 73). For more information, seeWhat Type of Queue Do I Need? (p. 2)Topics What Are the Main Benefits of Amazon SQS? (p. 1) How Is Amazon SQS Different from Amazon MQ or Amazon SNS? (p. 1) What Type of Queue Do I Need? (p. 2) How Can I Get Started with Amazon SQS? (p. 3) We Want to Hear from You (p. 3)What Are the Main Benefits of Amazon SQS? Security You control (p. 139) who can send messages to and receive messages from an AmazonSQS encryption (SSE) (p. 165) lets you transmit sensitive data by protecting the contents ofmessages in queues using keys managed in AWS Key Management Service (AWS KMS). Durability To ensure the safety of your messages, Amazon SQS stores them on multiple queues support at-least-once message delivery (p.

10 70), and FIFO queues support exactly-once message processing (p. 76). Availability Amazon SQS uses redundant infrastructure (p. 68) to provide highly-concurrentaccess to messages and high availability for producing and consuming messages. Scalability Amazon SQS can process each buffered request (p. 179) independently, scalingtransparently to handle any load increases or spikes without any provisioning instructions. Reliability Amazon SQS locks your messages during processing, so that multiple producers can sendand multiple consumers can receive messages at the same time. Customization Your queues don't have to be exactly alike for example, you can set a default delayon a Queue (p. 91). You can store the contents of messages larger than 256 KB using AmazonSimple Storage Service ( Amazon S3) (p. 92) or Amazon DynamoDB, with Amazon SQS holding apointer to the Amazon S3 object, or you can split a large message into smaller Is Amazon SQS Different from Amazon MQ orAmazon SNS?
