Fail over from GCP to AWS, or AWS to GCP. True multi-cloud disaster recovery.
Use cases:
Disaster recovery is high-stakes. FailZero includes multiple safety mechanisms to prevent bad failovers and ensure your system stays in a known state.
Before every failover, FailZero verifies your backup infrastructure is healthy. Check database replica status, instance group health, and endpoint responses. If any check fails, the failover is aborted - you never fail over to broken infrastructure.
If any step fails mid-failover, all previous changes are automatically reversed. DNS records are deleted or restored, compute instances are scaled back down, and secrets are reverted. No half-completed failovers, no manual cleanup.
Require human approval before automatic failover executes. Approval requests are sent via Slack/webhooks with one-click approve links. Set timeouts and fallback behavior (cancel or auto-approve).
Every failover is logged to database with full details: who triggered it, when, which steps executed, how long each took, and the complete result. Tamper-proof history for compliance and post-mortems.
Fast disaster recovery means less downtime. FailZero is optimized for speed at every stage.
3 health checks at 30-second intervals. Configurable threshold prevents false positives.
Database promotion takes 2-3 min. DNS and compute updates happen in seconds. Total recovery under 4 minutes.
Fully automated from detection to recovery. No runbooks, no manual intervention, no human error.
