GCP to AWS Cloud Migration for a Financial Services Organization

The client

The customer is a leading organization in the Financial Services industry, operating business-critical digital platforms that support investment operations, analytics, reporting, and internal financial workflows. These workloads demand high availability, strong security controls, data integrity, and predictable performance due to the sensitive nature of financial data and regulatory expectations. As part of its cloud optimization and modernization initiative, the customer decided to migrate its existing workloads from Google Cloud Platform (GCP) to Amazon Web Services (AWS). The primary objectives were to improve scalability, strengthen security posture, standardize operations on AWS, and leverage AWS-native migration and automation capabilities—all while ensuring minimal downtime and zero critical data loss.
