AWS provides four main messaging services: Amazon EventBridge, Amazon Kinesis, Amazon SQS, and Amazon SNS. Each has its own scaling constraints, cost structure, and error handling mechanisms. When choosing a service, consider throughput requirements, concurrency control needs, and potential costs. Error handling is facilitated by Lambda Destinations for EventBridge, SNS, and Kinesis, while SQS relies on dead letter queues. By understanding these factors and utilizing tools like decision trees and comparison tables, developers can select the most suitable messaging service for their serverless applications.
