SkyPilot's Resilient Fault Tolerant Architecture
To cope with the inherent instability of cloud environments, SkyPilot has designed a complete fault handling system. When a resource shortage, instance seizure, or hardware failure is detected, the system automatically triggers the recovery process without human intervention.
Core fault tolerance features include:
- Multi-level fault detection: real-time monitoring of instance status, network connectivity and task progress
- Intelligent Failover: Automatically switch to an alternate region or cloud platform when problems are encountered
- Checkpoint recovery: Supports task continuation from the most recent checkpoint to avoid wasted computing resources
In the bioinformatics batch task test, the system successfully handled 921 TP3T of sudden instance outages. Combined with the load balancing and replica mechanism of the Service Deployment (SkyServe) module, a service availability of 99.91 TP3T can be achieved.
