🔧 Technical Details

CORS Solution

The dashboard uses a custom CORS proxy server to handle browser security restrictions:

Browser → CORS Proxy (8080) → LocalStack (4566)

Infrastructure as Code

Includes CloudFormation templates for:

• S3 buckets with lifecycle policies
• DynamoDB tables with GSI
• Lambda functions with IAM roles
• API Gateway with custom domains

📊 Performance Benefits

• 90% faster local development cycles
• Zero AWS costs during development
• Instant feedback on infrastructure changes
• Offline development capabilities

🎯 Use Cases

Development Teams

• Local testing without AWS costs
• Integration testing in CI/CD pipelines
• Rapid prototyping of serverless applications

Learning & Training

• AWS services exploration without bills
• Infrastructure experimentation
• Serverless development practice

Production Readiness

• Pre-deployment testing
• Infrastructure validation
• Performance benchmarking
