The Challenge
Our client, a national financial services firm, was facing mounting costs and increasing risk from their aging on-premises data center infrastructure. With hardware refresh cycles approaching and regulatory pressure to improve disaster recovery capabilities, the leadership team made the strategic decision to migrate to the cloud.
However, this was no simple lift-and-shift. The firm's application portfolio included mission-critical trading platforms, real-time risk calculation engines, and customer-facing applications — all subject to strict financial regulatory requirements.
Our Approach
Phase 1: Discovery & Rationalization
We deployed automated discovery tools to map the complete application portfolio, including dependencies, data flows, and performance baselines. Each application was assessed against business criticality, technical complexity, and cloud readiness criteria.
Phase 2: Foundation & Landing Zone
Before migrating a single workload, we established a secure, compliant AWS landing zone with multi-account architecture, network segmentation, identity federation, and comprehensive logging and monitoring.
Phase 3: Wave-Based Migration
Applications were grouped into migration waves based on complexity and interdependencies. We started with lower-risk workloads to build confidence and refine our processes before tackling mission-critical systems.
Phase 4: Optimization
Post-migration, we implemented FinOps practices to continuously optimize costs, right-size resources, and leverage reserved capacity and spot instances where appropriate.
The Results
The migration was completed two months ahead of schedule with zero unplanned downtime. The firm now operates a modern, resilient cloud infrastructure that supports rapid innovation while exceeding regulatory compliance requirements.
