How Hypothekarbank Lenzburg future-proofed its open banking platform with Green

Increasing Demands Due to Finstar’s Success

What began as an ambitious open banking initiative has evolved into one of Switzerland’s leading banking ecosystems. At the center of this success is Finstar, a modern core banking platform built around an open API architecture. As daily transaction volumes surged from approximately 5,000 to 150,000, the platform expanded well beyond traditional banking customers. Today, fintech innovators such as neon, Kaspar&, and findependent also rely on Finstar as the technological foundation for their digital services.

As the platform grew, it became clear that the bank’s existing datacenter infrastructure would need to evolve as well. Increasing transaction volumes, higher availability requirements, and growing expectations around operational resilience called for a more future-ready architecture. «We need highly available systems that can deliver stronger resilience and business continuity,» explains Daniel Monras, Co-CEO of Finstar. As part of the evaluation process, physical security, redundant power and cooling systems, and the ability to build a highly available architecture across multiple locations became key decision criteria.

Building a Foundation for Future Growth

Together with Green, Hypothekarbank Lenzburg developed a new datacenter architecture that connects its existing environment with our Data Center ZRH3 Schlieren. The two sites are linked through redundant dark-fiber connections.

While the bank retains ownership and operation of its hardware through the Finstar team, Green provides the datacenter infrastructure and designed the connectivity solution connecting both locations. The project included:

• Dedicated cage with redundant dark-fiber connectivity between sites
• Redundant internet access
• Fit-out of the cage environment with cold-aisle containment, racks, PDUs, and access control systems
• Implementation of cabling and cross-connect infrastructure
• Customized reporting capabilities to support banking compliance requirements

Keeping Innovation Available Around the Clock

With its new datacenter architecture, Hypothekarbank Lenzburg now benefits from a significantly more resilient and future-ready infrastructure. Both locations can operate simultaneously in production, while each site is capable of handling the full workload independently if required. This substantially increases the availability and operational resilience of the Finstar platform.

The solution provides the scalability needed to support the platform’s continued expansion while meeting the highest standards for security, stability, and availability.
