Overview

High availability is not only infrastructure. It includes support processes, monitoring, recovery procedures, and realistic expectations about downtime.

Design Areas

  • Application redundancy
  • Database backup and recovery
  • Monitoring and alerting
  • Failover testing
  • Support ownership
  • Change control

Key Takeaways

Availability targets should be connected to business impact. A system that supports critical operations needs tested recovery procedures, not only redundant servers.
