event-driven-serverless-systems

To build an event-driven architecture on AWS, you integrate Lambda functions with event sources like SQS queues and SNS topics. This Skill guides you through implementing queue-based processing and pub/sub patterns for scalable serverless backends.

Managing distributed transactions in serverless microservices is best handled using AWS Step Functions to coordinate workflows. This approach implements the Saga pattern to maintain reliable state management and error handling across distributed services.

Use EventBridge instead of SNS for event routing when you need content-based filtering, schema registries, or third-party SaaS integrations. EventBridge supports the Event Router pattern for decoupled microservices, whereas SNS handles simple pub/sub fan-out scenarios.

Yes, this approach explicitly adheres to the AWS Well-Architected Framework for serverless design. It guides you through Well-Architected Serverless Design Principles to ensure efficient resource utilization, reliability, and operational excellence for your Lambda infrastructure.

Yes, you can use AWS MCP tools to deploy and execute Step Functions. This Skill leverages AWS MCP servers for SAM CLI, Lambda execution, and managing SNS/SQS and API Gateway integrations during infrastructure deployment.
