Challenge

NatWest Markets needed to build a secure, multi-regional application platform capable of supporting faster team onboarding and greater operational autonomy across its engineering organisation. The challenge was not just technical scale, it was regulatory precision. The platform had to satisfy strict financial services compliance and security policies, requiring consistent Kubernetes orchestration and advanced Istio service mesh traffic management across every environment. Legacy networking solutions were creating friction, and the absence of a unified control plane meant visibility across the estate was fragmented and unreliable.

Solution

We architected and delivered the OneBankFX platform on Google Cloud, built around Google Anthos as the foundation for unified cluster management, integrated observability, and Istio-based traffic control. Managed Services reduced operational overhead while Infrastructure-as-Code enforced consistency and auditability across all environments, ensuring every deployment met regulatory requirements by design rather than by manual check. Shared VPC capabilities replaced the legacy networking layer, giving NatWest Markets a more secure, scalable, and maintainable network architecture without compromising on control.

Outcomes

The OneBankFX platform gave NatWest Markets the consistent, compliant environments its engineering teams needed to move faster and with greater confidence. Onboarding became significantly quicker, team autonomy improved materially, and the bank gained a single, auditable source of truth across its multi-regional infrastructure. With legacy networking dependencies removed and a robust, cloud-native foundation in place, NatWest Markets is now positioned to scale its platform capability without accumulating further technical debt. Key stats include:
