Production Guide

Security Considerations

Secrets Management

• Never commit secrets to version control
• Use Kubernetes secrets for sensitive data
• Configure proper network policies

Network Security

• Configure ingress rules appropriately
• Use TLS for all external endpoints
• Implement proper RBAC policies

Resource Management

Resource Allocation

• Adjust resource requests/limits based on workload
• Monitor resource usage
• Implement horizontal pod autoscaling

Example HPA configuration:

apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
metadata:
  name: qelos-gateway
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: gateway-deployment
  minReplicas: 2
  maxReplicas: 10
  metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 80

High Availability

Multi-Zone Deployment

• Deploy across multiple availability zones
• Configure proper replica counts
• Use persistent storage for stateful services

Database Configuration

• Configure MongoDB replication
• Set up proper backup strategies
• Implement disaster recovery plans

Monitoring and Logging

Monitoring Setup

• Set up monitoring and alerting
• Configure proper logging
• Implement health checks

Recommended Tools

• Prometheus for metrics
• Grafana for visualization
• ELK stack for log aggregation
