GlobalBankDigitalTransformation
Fortune 500 Financial Institution
Complete digital transformation of legacy banking infrastructure across 50+ countries, migrating mission-critical systems to multi-cloud architecture while maintaining 24/7 operations and regulatory compliance.
The Challenge: Legacy Infrastructure at Scale
The bank faced critical challenges with aging infrastructure that threatened competitive position and operational efficiency.
System Performance
Legacy mainframe systems caused 15-minute transaction processing delays during peak hours
Customer satisfaction dropping 23% annually
Operational Costs
On-premises infrastructure costs were escalating 12% year-over-year
$180M annual infrastructure spend with declining efficiency
Security & Compliance
Fragmented security across 200+ legacy systems created compliance risks
Failed 3 regulatory audits in 18 months
Scalability Limitations
Unable to scale during peak trading volumes and seasonal demands
Lost $50M in potential revenue due to system unavailability
Our Approach: Zero-Downtime Cloud Migration
We designed and executed a comprehensive multi-cloud transformation strategy using advanced migration techniques and security frameworks.
