Overview
Lanka Finance PLC faced hardware obsolescence on their on-premise servers and needed a resilient disaster-recovery (DR) strategy. MillenniumPaths Foundation’s MillenniumIT ESP experts architected a full cloud migration to AWS, complete with automated failover and backup vaults.
The Challenge
Three mission-critical applications—Customer Portal, Loan Processing, and Financial Reporting—ran on EOL servers. Planned maintenance windows were ballooning to six hours, and unplanned outages threatened regulatory non-compliance. There was no off-site backup or automated failover in place.

Disaster Recovery & Backup
-
Configured cross-region snapshots in a secondary AWS region
-
Set up AWS Backup with lifecycle policies to meet a 30-day retention
-
Implementation Highlights
-
Executed blue/green deployments to avoid downtime
-
Enabled CloudWatch alarms and Lambda-driven auto-scaling
-
Conducted two “game-day” DR drills to validate RTO/RPO
Results

Reduced capital expenditure by 60%—no more hardware refresh cycles
-
RTO shortened to 10 minutes, RPO to 5 minutes
