Automatic Failover
If the primary server goes down, your application seamlessly switches to backup with zero downtime and no data loss.
Bir Konuşma BaşlatınWhy Choose This Service
Instant Switchover
Health checks detect failures in seconds and automatically route traffic to the backup server — no manual intervention needed.
Data Consistency
Real-time replication ensures the backup server has the same data as the primary — no transactions lost during failover.
Transparent to Users
Users never notice the switch. Same IP, same domain, same experience — just uninterrupted service.
Automatic Recovery
When the primary comes back online, data is synced and the system automatically resumes normal operation.
Nasıl Çalışıyoruz
Architecture Design
We design the failover architecture — replication topology, health checks, and DNS/IP failover strategy.
Setup & Testing
Configure replication, HAProxy, Keepalived, and run controlled failover tests to verify seamless switchover.
Monitoring & Drills
Continuous health monitoring with regular failover drills to ensure the system works when it matters most.

Frequently Asked Questions
How fast is the failover?
Health checks run every 2 seconds. When a failure is detected, traffic switches to the backup in 10-30 seconds. For most users, this appears as a brief page reload at worst.
Does failover work for databases too?
Yes. PostgreSQL streaming replication keeps the standby database synchronized in real-time. On failover, the standby promotes to primary automatically with zero data loss.
What is your uptime guarantee?
With automatic failover in place, we target 99.99% uptime (less than 53 minutes of downtime per year). Our monitoring detects and responds to issues before they affect users.
