+# AWS Lambda
+
+Build serverless applications with AWS Lambda.
+
+## Create Function
+
+```bash
+# Create function
+aws lambda create-function \
+  --function-name myfunction \
+  --runtime python3.11 \
+  --handler app.handler \
+  --role arn:aws:iam::xxx:role/lambda-role \
+  --zip-file fileb://function.zip
+
+# Update code
+aws lambda update-function-code \
+  --function-name myfunction \
+  --zip-file fileb://function.zip
+```
+
+## Function Code
+
+```python
+# app.py
+import json
+
+def handler(event, context):
+    return {
+        'statusCode': 200,
+        'body': json.dumps({'message': 'Hello!'})
+    }
+```
+
+## API Gateway Integration
+
+```bash
+# Create REST API
+aws apigateway create-rest-api --name myapi
+
+# Add Lambda permission
+aws lambda add-permission \
+  --function-name myfunction \
+  --statement-id apigateway \
+  --action lambda:InvokeFunction \
+  --principal apigateway.amazonaws.com
+```
+
+## Environment & Configuration
+
+```bash
+# Set environment variables
+aws lambda update-function-configuration \
+  --function-name myfunction \
+  --environment "Variables={DB_HOST=xxx,API_KEY=yyy}"
+
+# Set memory and timeout
+aws lambda update-function-configuration \
+  --function-name myfunction \
+  --memory-size 256 \
+  --timeout 30
+```
+
+## Best Practices
+
+- Minimize cold starts
+- Use layers for dependencies
+- Implement proper error handling
+- Use provisioned concurrency for latency-sensitive functions
+- Monitor with CloudWatch
