Kubernetes Production Deployment (Recommended)

# Deploy backend, redis, and postgres as separate components
kubectl create deployment medusa-backend --image=medusajs/medusa:latest
kubectl expose deployment medusa-backend --port=9000

• Horizontal Scaling: Scale the Medusa backend pods to handle peak traffic during sales events.
• Resilient Infrastructure: Automatically restart unhealthy app instances and handle failovers.
• Secret Management: Securely manage API keys for Stripe, PayPal, and other providers.

Scaling Strategy

• Separate Workers: Run Medusa workers as separate pods to handle long-running background tasks.
• Database Optimization: Use managed PostgreSQL with read-replicas for catalog browsing.
• CDN Caching: Always use a CDN for your storefront and to serve product images globally.
• Redis Clustering: For very large stores, use a Redis cluster to handle job queues and sessions.

Backup & Security

• Daily Backups: Automate PostgreSQL dumps and store them offsite.
• HTTPS Enforcement: Always run Medusa behind a secure reverse proxy with SSL/TLS.
• Token Rotation: Regularly rotate your JWT and cookie secrets.
• Limited Access: Restrict the Admin dashboard to internal IP addresses or your private VPN.
