Modernizing Infrastructure to Fuel Global Financial Operations

For a leading global financial services organization, outdated infrastructure wasn’t just slowing them down, it was jeopardizing agility and continuity. Provisioning delays, high maintenance overheads, and scalability limitations were becoming bottlenecks.

The challenge? Migrating hundreds of tightly coupled workloads with no room for disruption to mission-critical systems.

That’s where AHEAD stepped in.

The Challenge: A Delicate Balancing Act Between Scale and Stability

• Zero Tolerance for Downtime: Trading platforms and transactional databases had to stay online throughout.
• Unmapped Application Dependencies: Complex interconnections weren’t fully documented.
• Regulatory Pressure: The organization needed to meet strict compliance and data governance standards.
• Scalability Limits: Legacy systems couldn’t scale on demand, slowing innovation.

AHEAD’s Approach: Discovery-Led Strategy, Execution at Scale

• Discovery-Driven Strategy: AHEAD began with a comprehensive discovery phase to map application and system interdependencies. This informed migration wave planning and ensured controlled execution.
• Seamless Execution at Scale: Using AWS MGN (Application Migration Service), AHEAD conducted a phased lift-and-shift migration to EC2, ensuring uninterrupted performance for business-critical systems – even during active production hours.
• Disaster Recovery with Sub-Second RTO: A separate AWS account was set up for disaster recovery using AWS DRS, with automated failover and sub-second RTO.
• Security & Compliance: A Zero Trust model was implemented using AWS IAM, Privatelink, AWS Shield, and other native tools to meet rigorous financial industry standards.
• Key elements included:
  • Wave planning based on criticality and interdependencies
  • Zero-trust security implementation via AWS-native services
  • One-touch automation deployments at every stage
  • FinOps-aligned cost-performance balance

Results: A Future-Ready Cloud Foundation Delivered Without Disruption

• Zero Downtime Migration: All systems, including trading platforms, were migrated during business hours without disruption.
• Enhanced Scalability: Faster provisioning and dynamic workload scaling were enabled post-migration.
• Cost Optimization: Infrastructure overhead was reduced and ROI improved, driven by FinOps strategies.
• Compliance Assurance: Full adherence to industry and regulatory compliance frameworks throughout the engagement.

What’s Next: Driving Deeper Cloud Maturity

With the foundational migration complete, the client is now focused on:

• Containerization using AWS ECS and Fargate for serverless workloads
• Advanced observability through Amazon CloudWatch, AWS X-Ray, and cloud-native automation
• Continuous cost optimization and performance tuning as part of a cloud maturity roadmap

Together, AHEAD and the client are shaping a resilient, secure, and future-ready cloud ecosystem.
