dns High Availability (HA)
HA aims to eliminate single points of failure. The goal is to keep the application running despite component failures (e.g., a server crash).
Key Concepts
- check_circle Redundancy: Duplicating critical components.
- check_circle Load Balancing: Distributing traffic across healthy nodes.
- check_circle Failover: Automatically switching to a backup.
