## Description

Design, build, deploy, test, and debug serverless applications with AWS Lambda. Triggers on phrases like: Lambda function, event source, serverless application, API Gateway, EventBridge, Step Functions, serverless API, event-driven architecture, Lambda trigger. For deploying non-serverless apps to AWS, use deploy-on-aws plugin instead.

# AWS Lambda Serverless Development

Design, build, deploy, and debug serverless applications with AWS serverless services. This skill provides access to serverless development guidance through the AWS Serverless MCP Server, helping you to build production-ready serverless applications with best practices built-in.

Use SAM CLI for project initialization and deployment, Lambda Web Adapter for web applications, or Event Source Mappings for event-driven architectures. AWS handles infrastructure provisioning, scaling, and monitoring automatically.

**Key capabilities:**

- **SAM CLI Integration**: Initialize, build, deploy, and test serverless applications
- **Web Application Deployment**: Deploy full-stack applications with Lambda Web Adapter
- **Event Source Mappings**: Configure Lambda triggers for DynamoDB, Kinesis, SQS, Kafka
- **Lambda durable functions**: Resilient multi-step applications with checkpointing, see the [durable-functions skill](../aws-lambda-durable-functions/) for guidance
- **Lambda Managed Instances**: Run Lambda on dedicated EC2 instances with managed lifecycle, see the [managed-instances skill](../aws-lambda-managed-instances/) for evaluation, configuration, and migration guidance
- **Schema Management**: Type-safe EventBridge integration with schema registry
- **Observability**: CloudWatch logs, metrics, and X-Ray tracing
- **Performance Optimization**: Right-sizing, cost optimization, and troubleshooting
