Automatic disaster recovery

Outages happen. Recovery does, too.

Why FailZero

3 minutes

Failure detected. Database promoted. Compute scaled. DNS switched. Done.

Zero credentials

Our agent runs in your VPC using credentials only you have access to.

YAML, not runbooks

Version controlled. Pre-flight checked.

Supported Platforms

AWS
Google Cloud
Azure (ETA 2026)
Multi-Cloud

RDS

Promote read replicas to primary. Get new endpoint addresses automatically. Update connection strings across your infrastructure.

Route53

Update DNS records to failover regions. Automatic rollback on failure. Support for A, CNAME, AAAA, and TXT records.

EC2 & ECS

Scale Auto Scaling Groups or ECS Services. Automatic detection of compute type. Ensure backup capacity before switching traffic.

Secrets Manager

Update database connection strings, API keys, and configuration. Automatic rollback to previous values if needed.

Cloud SQL

Promote read replicas to primary. Get new endpoint IPs automatically. Update connection strings across your infrastructure.

Cloud DNS

Update DNS records to failover regions. Automatic rollback on failure. Sub-second DNS propagation.

Compute Engine

Scale managed instance groups up or down. Ensure backup capacity before switching traffic. Health checks before failover.

Secret Manager

Update database connection strings, API keys, and configuration. Automatic rollback to previous values if needed.

Azure support coming Q3 2026. Azure DNS, Azure SQL Database, VM Scale Sets, Key Vault.

Fail over from GCP to AWS, or AWS to GCP. True multi-cloud disaster recovery.

Use cases:

  • GCP primary → AWS backup (cross-cloud redundancy)
  • AWS primary → GCP backup (cross-cloud redundancy)
  • Progressive migration (shift 10% → 50% → 100%)
  • Vendor lock-in protection

Built for Production

Disaster recovery is high-stakes. FailZero includes multiple safety mechanisms to prevent bad failovers and ensure your system stays in a known state.

Pre-flight Checks

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.

Automatic Rollback

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.

Approval Workflow

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).

Complete Audit Trail

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.

Performance

Fast disaster recovery means less downtime. FailZero is optimized for speed at every stage.

90s
Detection Time

3 health checks at 30-second intervals. Configurable threshold prevents false positives.

3min
Recovery Time

Database promotion takes 2-3 min. DNS and compute updates happen in seconds. Total recovery under 4 minutes.

Manual Steps

Fully automated from detection to recovery. No runbooks, no manual intervention, no human error.
