Failover
A resilience design pattern in distributed systems that automatically switches from a primary service to a backup service when the primary becomes unavailable. Commonly applied in LLM API call scenarios to handle rate limiting and service outages.
Timeline (last 90 days)
Fallback in distributed systems refers to a fault-tolerance pattern in which the system automatically switches to a backup path when the primary path fails.
When an AI service provider experiences a failure or hits a rate limit, OmniRoute automatically routes requests to the next healthy provider, achieving automatic failover.
The core logic of a multi-provider failover mechanism is: when the primary provider returns 429 or other retryable errors, automatically switch to a backup provider instead of letting the request fail outright.
Failover relies on two core mechanisms: shared state and health checking, with shared state typically implemented via distributed databases or consensus protocols such as Raft
TrustedRouter has a built-in provider failover mechanism that can automatically switch requests to a backup route when a model provider experiences downtime, rate limiting, or latency spikes
Failover requires three elements: fault detection, state preservation (via checkpointing mechanisms), and intelligent rescheduling.
