Google Cloud Fault Injection Testing: Native Resilience Validation for Cloud Hosts
Modern distributed cloud hosting makes high availability harder, not easier. When a managed database or network path fails, your services must stay online, but traditional self-hosted failover drills do not translate cleanly to shared cloud infrastructure. Google Cloud recently introduced Fault Injection Testing (FIT) in preview, a native service that lets architects inject controlled faults into Cloud SQL, load balancers, and compute resources to verify resilience before a real incident. For hosting providers, enterprise sites, and sysadmins running mission-critical workloads, the tool promises to close a dangerous gap between assumed and proven redundancy. This article breaks down what FIT does, where it fits in your reliability workflow, and what to watch during the preview.
