AWS Messaging & Streaming Services

When answering AWS messaging and streaming questions, verify specific numbers, versions, limits, and behavioral details from service-specific skills or official AWS documentation. When uncertain, search skills or docs rather than guessing. Fabricated configuration options or incorrect version numbers are worse than admitting uncertainty.

When a question asks about recommended configurations (CloudWatch alarm settings, thresholds, missing data treatment), search for the service-specific skills or documentation rather than relying on general best practices.

Overview

Domain expertise for choosing and using AWS services that move data between producers and consumers. This skill covers two fundamental patterns — messaging and streaming — and the AWS services that implement each. Use this skill to decide which pattern fits a workload, select the right service, and understand how services integrate with each other.

For specific guidance on individual AWS services, see reference files or service-specific Skills.

Streaming and Messaging

What Is Messaging?

Messaging enables decoupled, asynchronous communication between components. A producer sends a message; one or more consumers receive and process it. Once processed, the message is typically deleted. Messaging services handle delivery guarantees, retries, and dead-letter routing.
