Component High Availability​

API Service​

  • Multiple Instances: Run multiple API service instances
  • Load Balancing: Use load balancer to distribute requests
  • Health Checks: Automatically remove unhealthy instances

Database​

  • Master-Slave Replication: MySQL master-slave replication
  • Read-Write Separation: Read operations access slave database
  • Automatic Failover: Automatically switch when master fails

Redis​

  • Sentinel Mode: Redis Sentinel
  • Cluster Mode: Redis Cluster
  • Automatic Failover: Automatically switch master node

Monitoring and Alerts​

  • Service Monitoring: Monitor service health status
  • Resource Monitoring: Monitor CPU, memory and other resources
  • Alert Notifications: Notify promptly on anomalies

Backup and Recovery​

  • Data Backup: Regularly backup database
  • Configuration Backup: Backup configuration files
  • Quick Recovery: Support quick service recovery
