Architecture Overview
The Hub platform consists of:- Backend: Spring Boot 3 application (Java 21)
- Frontend: Next.js application
- Database: PostgreSQL 16 with PostGIS extension
- Auth: Auth0 OAuth2/JWT authentication
- Storage: Cloudinary for image uploads
- Email: SMTP-based email service
Deployment Options
Container-Based Deployment
Recommended for cloud platforms and Kubernetes:- AWS ECS/Fargate
- Google Cloud Run
- Azure Container Instances
- Kubernetes (EKS, GKE, AKS)
- Docker Swarm
Platform-as-a-Service
Managed platforms for simplified deployment:- Heroku
- Render
- Railway
- Fly.io
Traditional VPS
For custom infrastructure:- DigitalOcean Droplets
- AWS EC2
- Linode
- Hetzner Cloud
Environment Variables
All required environment variables for production:Database Configuration
Authentication (Auth0)
Configure Auth0 callback URLs to match your production domain.
Cloudinary (Image Storage)
Email Configuration
Application Settings
Optional Configuration
Security Best Practices
1. Database Security
Use strong credentials
- Generate complex passwords (minimum 32 characters)
- Use different credentials for each environment
- Rotate passwords periodically
2. Application Security
Required configurations:application.yaml
3. API Security
- Disable Swagger: Set
SWAGGER_ENABLED=false - Configure CORS: Restrict frontend origins
- Rate limiting: Implement API rate limits
- JWT validation: Verify Auth0 tokens properly
4. Secrets Management
Recommended approaches:Database Setup
PostgreSQL with PostGIS
Provision managed database
Use a managed PostgreSQL service:
- AWS RDS for PostgreSQL
- Google Cloud SQL
- Azure Database for PostgreSQL
- DigitalOcean Managed Databases
- Supabase
Database Migrations
The application uses Flyway for schema management:application.yaml
Migrations run automatically on application startup. Ensure proper backup before deploying schema changes.
Backend Deployment
Building the Application
Container Orchestration
Kubernetes Deployment Example
deployment.yaml
Docker Compose Production
docker-compose.prod.yml
Performance Optimization
JVM Tuning
Optimize Java runtime for production:Database Connection Pooling
Caching Strategy
Consider implementing:- Redis for session storage
- Application-level caching with Caffeine
- HTTP caching headers for static resources
Monitoring and Logging
Health Checks
The application exposes health endpoints:GET /actuator/health- Application health statusGET /actuator/info- Application information
Logging Configuration
Structured logging for production:The application includes trace IDs in logs for distributed tracing.
Monitoring Tools
Recommended monitoring solutions:- APM: New Relic, Datadog, Dynatrace
- Logging: ELK Stack, Splunk, Loki
- Metrics: Prometheus + Grafana
- Error tracking: Sentry, Rollbar
Backup and Recovery
Database Backups
Configure automated backups
Enable automated backups in your managed database service (daily recommended).
Application State
- User uploads: Backed up automatically by Cloudinary
- Configuration: Store in version control
- Secrets: Backed up by secrets management service
Scaling Considerations
Horizontal Scaling
The backend is stateless and can be scaled horizontally:Kubernetes
Database Scaling
Options for database scaling:- Vertical: Increase instance size
- Read replicas: For read-heavy workloads
- Connection pooling: PgBouncer for connection management
Load Balancing
Recommended load balancers:- AWS Application Load Balancer
- Google Cloud Load Balancing
- Nginx
- Traefik
Deployment Checklist
Before deploying to production:- All environment variables configured
- Database SSL mode set to
require - Swagger disabled (
SWAGGER_ENABLED=false) - Strong database credentials generated
- Auth0 production tenant configured
- Cloudinary production account set up
- Email service configured and tested
- Database backups enabled
- Monitoring and alerting configured
- Health checks implemented
- Load testing completed
- SSL/TLS certificates installed
- Domain DNS configured
- Firewall rules configured
- Secrets stored in secrets manager
Troubleshooting
Application Won’t Start
-
Check environment variables are set:
-
Verify database connectivity:
- Check application logs for specific errors
Database Connection Issues
- Verify SSL mode matches database configuration
- Check firewall rules allow application IP
- Confirm credentials are correct
- Test network connectivity to database host
Performance Issues
- Review database query performance
- Check connection pool settings
- Monitor JVM memory usage
- Analyze application logs for slow requests
Next Steps
- Set up Docker for local development
- Configure CI/CD pipelines
- Review Security best practices
