Which service is involved in enabling message queuing between producers and consumers?

Amazon SQS (Simple Queue Service) is specifically designed to enable message queuing between producers and consumers in a distributed system. It provides a reliable, highly scalable, and fully managed message queuing service that allows users to decouple and scale microservices, distributed systems, and serverless applications. Producers send messages to a queue, and consumers retrieve those messages at their own pace, which helps ensure that no messages are lost and can be processed even if consumers are temporarily slow or unavailable.

In contrast, while Amazon SNS (Simple Notification Service) is utilized for sending messages to multiple subscribers or endpoints, it doesn't provide persistent messaging like SQS does; it’s primarily for pub/sub messaging rather than direct queue management. AWS Batch is a service designed for running batch computing jobs, which is not related to message queuing. Amazon Kinesis Data Streams focuses on real-time data streaming and is used for collecting and processing large streams of data, but it does not serve as a queuing mechanism in the way SQS does. Hence, Amazon SQS is the most suitable service for the task of enabling message queuing between producers and consumers.
