AWS Serverless Microservices with Patterns and Best Practices - Amazon SQS Architecture and How SQS Works - The Lifecycl

The video tutorial explains the architecture and lifecycle of Amazon SQS messages. It covers the three main components of SQS: producers, consumers, and the queue. The message lifecycle is detailed from creation to deletion, highlighting the visibility timeout feature that prevents message reprocessing. This feature is crucial for developing reliable applications, such as e-commerce platforms.

What are the three main components of a distributed messaging system in Amazon SQS?

• It remains in the queue and is not returned to subsequent requests

• It is archived for future reference

• It is deleted from the queue

• It is visible to other consumers
