Disaster Recovery Solution

A comprehensive disaster recovery architecture that provides multi-region resilience with automated failover and sub-hour recovery objectives.

The Challenge

A financial services company had inadequate DR:

• Single region - All infrastructure in one location
• Manual recovery - DR process in a binder
• Long RTO - Days to recover from disaster
• Untested - DR plan never actually tested

They needed automated, tested disaster recovery.

Our Approach

We built an active-passive multi-region architecture with automation.

DR Strategy

1. Multi-Region - Geographic redundancy
2. Automated Failover - No manual intervention needed
3. Continuous Replication - Near-real-time data sync
4. Regular Testing - Quarterly DR drills

The Solution

Data Replication

• Database cross-region replication
• Object storage mirroring
• Message queue replication
• Configuration sync

Failover Automation

• Health check monitoring
• Automatic DNS failover
• Database promotion scripts
• Traffic rerouting

DR Testing

• Regular failover drills
• Chaos engineering
• Runbook automation
• Post-mortem analysis

Documentation

• Recovery runbooks
• Contact procedures
• Escalation paths
• Communication templates

Technology Stack

Results & Impact

The DR solution achieved its objectives:

• 15-minute RTO - Full recovery in minutes
• 5-minute RPO - Near-zero data loss
• Zero data loss in quarterly DR tests
• Automated failover with no manual steps

DR Capabilities

Failure Scenarios

• Region-wide outages
• Database failures
• Network partitions
• Application failures

Testing Program

• Quarterly full failover tests
• Monthly component tests
• Chaos engineering exercises
• Tabletop exercises

Client Testimonial

"We went from a paper-based DR plan to automated failover in 15 minutes. The quarterly tests give us confidence that it actually works."
