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.
