Classify messaging services to use cases

AWS gives you several messaging services for connecting the parts of an event-driven application, and each is a natural fit for a different job. Amazon SQS is a queue for decoupling a producer from a consumer, Amazon SNS fans out a message to many subscribers, Amazon EventBridge routes events by content using rules, and Amazon Kinesis Data Streams ingests high-throughput streams for real-time processing. Match each use case to the service that fits it best.
