Core CDK Principles

Resource Naming

Do NOT explicitly specify resource names when they are optional in CDK constructs.

// ✅ GOOD - Let CDK generate unique names
new lambda.Function(this, 'MyFunction', {
  // No functionName specified
});

// ❌ BAD - Prevents multiple deployments
new lambda.Function(this, 'MyFunction', {
  functionName: 'my-lambda',
});

Lambda Functions

Use appropriate constructs for automatic bundling:

• TypeScript/JavaScript: NodejsFunction from aws-cdk-lib/aws-lambda-nodejs
• Python: PythonFunction from @aws-cdk/aws-lambda-python-alpha

Pre-Deployment Validation

Before committing CDK code:

npm run build
npm test
npm run lint
cdk synth
./scripts/validate-stack.sh

Usage Examples

CDK Development

Ask Claude to help with CDK:

Create a CDK stack with a Lambda function that processes S3 events

Claude will:

• Follow CDK best practices
• Use NodejsFunction for automatic bundling
• Avoid explicit resource naming
• Grant proper IAM permissions
• Use MCP servers for latest AWS information

Cost Optimization

Estimate costs before deployment:

Estimate the monthly cost of running 10 Lambda functions with 1M invocations each

Analyze current spending:

Show me my AWS costs for the last 30 days broken down by service

Monitoring and Observability

Set up monitoring:
