Kubernetes Production Deployment (Recommended)

# Use official Helm charts to deploy the entire ecosystem
helm repo add reaction https://helm.reactioncommerce.com
helm install my-commerce reaction/reaction --namespace production

• Horizontal Pod Autoscaling: Automatically scale individual commerce services based on real-time load.
• Self-Healing Infrastructure: Ensure that any failed service is immediately replaced without downtime.
• Enterprise Security: Securely manage API secrets and cloud-service connections via Kubernetes Secrets.

Scaling Strategy

• Elasticsearch Deployment: Always use an Elasticsearch cluster for catalog search in production environments.
• Distributed Caching: Leverage Redis to handle high-frequency cache requests across all service pods.
• Independent Scaling: Monitor your 'Order' and 'Catalog' services separately and scale them based on specific bottlenecks.
• CDN Strategy: Use a global CDN to serve storefront assets and cached GraphQL responses.

Backup & Safety

• Multi-DB Backups: Automate daily backups for both PostgreSQL (transactions) and MongoDB (catalog).
• Cross-Region Replication: In large setups, replicate your storage tiers across different regions for disaster recovery.
• Monitoring: Use a full-stack observability tool like Datadog or Prometheus/Grafana to track microservices health.
• Strict API Security: Enforce modern authentication patterns and regularly audit your GraphQL permissions.
