A leading global financial services institution managing over $500B in assets needed to modernize their legacy on-premise infrastructure to reduce operational costs, improve scalability, and accelerate time-to-market for new digital banking products. Their 15-year-old data center infrastructure was becoming increasingly expensive to maintain and couldn't support the agility required for digital transformation.

Project Overview
The Challenge
1. Escalating Infrastructure Costs
Operating five global data centers cost $45M annually, with costs increasing 12% year-over-year. Hardware refresh cycles required $8M capital expenditure every 3-4 years. Energy and cooling costs alone exceeded $6M annually.
- $45M annual operational costs with 12% YoY increase
- $8M hardware refresh required every 3-4 years
- Over-provisioned capacity sitting idle 60% of the time
2. Limited Scalability & Agility
Provisioning new infrastructure took 4-6 weeks, preventing rapid response to market opportunities. Peak processing periods (quarter-end, tax season) required permanent over-provisioning. Development teams waited days for test environments.
- 4-6 weeks to provision new infrastructure
- Unable to scale dynamically for seasonal demand
3. Compliance & Security Concerns
Meeting regulatory requirements (SOC 2, PCI DSS, GDPR) across disparate on-premise systems was complex and resource-intensive. Annual compliance audits consumed 3,000+ staff hours. Disaster recovery testing required full production shutdown.
4. Technical Debt & Legacy Systems
200+ applications built on aging infrastructure, many using end-of-life software. Monolithic architecture made updates risky. No containerization or microservices. Limited automation capabilities.
The Solution
Hybrid Cloud Architecture
We designed and implemented a hybrid cloud architecture leveraging AWS for scalable workloads and Azure for Microsoft-dependent applications, while maintaining on-premise infrastructure for highly regulated trading systems requiring ultra-low latency.
AWS Primary Cloud
Customer-facing applications, data analytics, microservices
Azure Secondary
Microsoft workloads, AD integration, Office 365
Application Modernization
Containerized 150+ applications using Kubernetes, refactored 40 critical applications to microservices architecture, and implemented CI/CD pipelines for automated deployment.
- 150+ applications containerized with Kubernetes
- 40 monoliths refactored to microservices
- Full CI/CD automation with GitLab and Jenkins
Security & Compliance Framework
Implemented comprehensive security controls including encryption at rest and in transit, identity and access management with MFA, automated compliance monitoring, and real-time threat detection.
Results & Outcomes
