The challenge:Modernising Legacy Core Banking Systems

Built more than two decades ago, our customer’s core banking systems were tightly coupled and highly complex, weighed down by extensive third‑party dependencies, significant technical debt, and large volumes of unstructured and obsolete data. Modernising and migrating these systems to a GCP environment required overcoming substantial technical and operational challenges.

• Migration Complexity: A simple lift‑and‑shift migration approach could not be adopted as each legacy system required extensive code refactoring, dependency decoupling, data rationalisation, and environment re‑engineering before deployment to GCP.
• Vanilla Ecosystem: The target migration environment was provided as a fully vanilla cloud setup, with a strict mandate to rely exclusively on native cloud services to adhere to cost, security, and governance requirements.
• Delivery Risks: While our customer’s leadership had committed to setting up the cloud infrastructure and migrating the ten most critical core banking systems within a year, traditional migration approaches posed significant risks to delivery timelines and operational stability.
• Cloud Flexibility: A scalable, cloud-agnostic solution needed to be implemented to avoid dependencies on a single cloud provider like GCP, as future migrations across Azure, AWS, and/or other cloud platforms were anticipated as part of our customer’s long‑term digital transformation roadmap.
