Summary

• A message queue is a queue of messages exchanged between applications.
• Messages are data objects that are inserted in the queue by sender applications and received by the receiving applications.
• SQS can save an application from getting flooded with messages by storing them into a queue.
• Applications can process the messages without getting interrupted.
• SQS can be used for decoupling application processes.
• SQS provides scalability to an application environment.
• The use of a message queue ensures that a message is delivered at least once, and it is eventually processed by the processing application as long as the process continues reading the queue.
• SQS provides a mechanism to process the data in a predefined order.
• SQS allows you to process the messages asynchronously.
• SQS builds resilience in the system.
• SQS brings elasticity to applications.
• SQS can easily help identify...
