GLOSSARY > HIGH AVAILABILITY

High Availability

A characteristic of a system that aims to ensure an agreed level of operational performance, usually uptime, for a higher than normal period.

High Availability (HA) architectures eliminate single points of failure. For mission-critical AI, HA requires redundant LLM inference nodes, load balancers, and distributed Vector Databases spread across multiple geographic zones to ensure continuous operational intelligence even during catastrophic hardware failures.
