High Scale Integrations in Finance

Introduction

This case study highlights work completed for CU Direct, now known as Origence, a leading provider of lending technology solutions for credit unions. Since 1994, the company has helped credit unions deliver efficient, member-focused lending experiences through configurable lending platforms, analytics, retail lending solutions, mobile technologies, and digital lending tools.

As the company continued to expand its lending platform, it sought to modernize the integration layer connecting its internal and external systems. The existing architecture relied on Microsoft BizTalk Server to orchestrate communication between business applications and third-party services. While effective for many years, the aging platform introduced licensing costs, maintenance challenges, and limited flexibility for future development.

The primary objective was to replace the legacy integration platform with a modern, scalable messaging architecture that would reduce operational overhead while supporting future growth.

Challenge

The client's existing integration platform depended on Microsoft BizTalk Server 2006, which orchestrated communication between numerous internal and external applications through custom workflows and proprietary ICE records used to route and execute services.

This architecture presented several challenges:

• Legacy integration platform

  
  

  BizTalk Server required ongoing licensing, maintenance, and specialized expertise while limiting modernization efforts.

• Complex service orchestration

  
  

  Custom orchestrations and ICE records created tight coupling between systems, making integrations difficult to extend and maintain.

• Scalability limitations

  
  

  The existing solution made it increasingly difficult to introduce new integrations and support future business growth efficiently.

Solution

Afterman Software partnered with the client to replace BizTalk Server with a modern messaging architecture built on NServiceBus, eliminating legacy dependencies while preserving existing business functionality.

The new solution emphasized scalability, modularity, and maintainability through an event-driven architecture capable of supporting future integrations.

Event-Driven Messaging

NServiceBus replaced custom BizTalk orchestrations with reliable asynchronous messaging, simplifying communication between distributed systems while improving resiliency.

Scalable Integration Architecture

The platform was redesigned to support loosely coupled services, making future integrations significantly easier to develop, deploy, and maintain.

Reduced Operational Costs

By eliminating BizTalk licensing requirements, the client immediately reduced infrastructure costs while gaining a more flexible and extensible platform for continued innovation.

Outcome

Migrating from BizTalk Server to NServiceBus successfully modernized the client's integration platform while maintaining existing business operations. The new architecture reduced licensing costs, improved scalability, simplified future integrations, and established a flexible foundation capable of supporting continued product growth and evolving business requirements.
