The Database Ninja team designs, deploys, and operates high availability and disaster recovery architectures across every major database platform. Architecture you can trust, runbooks that actually work, and failover events that are non-events.

High Availability and Disaster Recovery
Overview

HA architectures that work when you need them.

Most high availability deployments are tested only when they fail in production for the first time. That is when teams discover that the failover was untested, the runbook is wrong, the standby is behind, or the application cannot reconnect cleanly. The Database Ninja team designs HA architectures with the assumption that they will fail and the certainty that we will rehearse the failure beforehand.

We work across Oracle Data Guard and RAC, PostgreSQL Patroni, MySQL InnoDB Cluster and Group Replication, and SQL Server Always On Availability Groups. We design topologies that match your real RTO and RPO requirements. We test them under realistic failure conditions. We document what actually works and what does not.

For disaster recovery, we plan beyond the database itself. Application reconnection logic, DNS failover, cross-region data movement, and the operational runbooks that make a regional outage a recoverable event instead of a catastrophic one.

What's Included

What HA and DR engagements cover.

HA Architecture Design

Topology design tailored to your real RTO and RPO needs. Not the marketing version, the actual numbers your business can tolerate.

Failover Implementation

Deployment of automated failover, configuration of split-brain protection, and integration with your DNS and load balancing layers.

Failover Testing

Realistic failure injection in non-production environments. We rehearse every failure mode before it happens in production.

DR Planning

Cross-region replication, point-in-time recovery design, and recovery runbooks for the worst case scenarios.

Runbook Authorship

Step-by-step procedures your on-call engineers can execute under pressure. Tested and reviewed, not theoretical.

Ongoing Validation

Quarterly DR drills with your team to verify the architecture still works after every change.

Why Database Ninja

Why HA work needs senior hands.

Real failure experience

We have responded to real production database outages. We know the difference between a tested HA setup and one that just looks good on paper.

Vendor-deep expertise

Data Guard, Patroni, InnoDB Cluster, Always On. The configuration nuances matter. We have the scars from each one.

Application-aware design

The database is only half the story. We design HA that includes how your application reconnects, retries, and recovers state.
