Building a Modern Application Infrastructure for Digital Banking at Scale

How TeraSky helped a leading European financial institution create a resilient, enterprise-grade application platform powered by Kubernetes

Customer Profile

A leading European financial institution serving millions of customers across multiple markets. As digital banking became a primary customer channel, the organization needed a modern application infrastructure capable of supporting rapid growth, stringent security requirements, and always-on digital services.
Today, the majority of the bank’s customers interact through digital channels, making application availability, performance, and scalability critical to business success.

The Challenge

The bank’s digital transformation strategy required a fundamental shift in how applications were built, deployed, and managed.
As adoption of mobile and online banking accelerated, existing infrastructure approaches were no longer sufficient to support the scale, agility, and resilience required by modern financial services.

The organization needed to:

• Create a scalable application infrastructure capable of supporting growing digital demand
• Standardize application deployment and operations across multiple locations
• Improve platform resilience and availability for mission-critical banking services
• Accelerate delivery of cloud-native applications
• Strengthen operational governance and security
• Enable development teams to adopt modern DevOps practices

The bank recognized that achieving these objectives would require an enterprise-grade platform designed specifically for modern applications.

The Solution

Following a comprehensive assessment, TeraSky designed and implemented a modern application infrastructure platform based on VMware Tanzu and Kubernetes.
The initiative was delivered in two strategic phases focused on platform modernization and organizational enablement.

Phase 1: Enterprise Application Platform Deployment

TeraSky implemented a centralized Kubernetes-based application platform spanning three production sites, providing a resilient foundation for cloud-native applications and critical banking services.

The new platform delivered:

• Enterprise-grade Kubernetes infrastructure
• High availability across multiple locations
• Standardized application deployment and lifecycle management
• Improved scalability for customer-facing banking services
• Consistent operational governance and security controls

In parallel, existing cloud-native applications were migrated to the new production platform while maintaining strict service-level requirements.

Phase 2: Operational Enablement and DevOps Adoption

Technology transformation extends beyond infrastructure.
To ensure long-term success, TeraSky worked closely with the bank’s engineering and operations teams, providing training, operational guidance, and Kubernetes best practices.

• This phase focused on:
• DevOps enablement and knowledge transfer
• Platform operations best practices
• Kubernetes administration and governance
• Application lifecycle management
• Cloud-native operational processes

The result was not only a new platform, but also the internal capability required to operate and evolve it successfully.

The Results

The modern application infrastructure became a critical enabler of the bank’s digital transformation strategy.
