- DynamoDB tables with GSI indexes
- S3 bucket with versioning and CORS
- SQS queues with DLQ support
- Lambda functions with proper IAM roles
- API Gateway with CloudFront distribution
- CloudWatch logging and monitoring
### 5. Monitoring & Observability
- **CloudWatch Metrics** (`src/monitoring/cloudwatch-metrics.ts`)
- Custom business metrics
- Performance monitoring
- Error tracking
- Usage analytics
### 6. Deployment & Operations
- **Deployment Scripts** (`scripts/deploy-aws.sh`)
- Automated AWS deployment
- CDK bootstrap and deployment
- Environment configuration
- Health checks and validation
- **Docker Support**
- Multi-stage Dockerfile
- Production-ready container
- Health checks
- Optimized for AWS Lambda
### 7. Testing & Quality
- **Build System**: TypeScript compilation with SWC
- **Code Quality**: ESLint, TypeScript strict mode
- **Package Management**: PNPM with proper dependency management
- **Version Control**: Git with proper commit messages
## 🏗️ Architecture Highlights
### Key Features
- **Serverless Architecture**: Fully serverless with AWS Lambda
- **Event-Driven**: SQS for async processing
- **Scalable**: Auto-scaling DynamoDB and Lambda
- **Cost-Effective**: Pay-per-use model
- **Global**: CloudFront CDN for worldwide access
- **Secure**: IAM roles, VPC endpoints, encryption
### Performance Optimizations
- **Caching**: Multi-level caching strategy
- **Indexing**: Optimized DynamoDB GSI indexes
- **CDN**: CloudFront for static content
