About CU Loan Source

CU Loan is a forward-thinking and member-owned financial cooperative committed to providing accessible banking services. With a mission rooted in reinvesting profits back into its members, CU Loan Source focuses on reducing fees and delivering unique financial services.

Challenge

  • Incompatible legacy VB6 System
  • Lagging database queries and bloated code functions hindered responsiveness. 
  • Time-consuming manual report generation and file handling.
  • Sensitive data lacked encryption, and the system lacked role-based access controls.

CU Loan Source faced slow performance, security risks due to an outdated legacy system, and a monolithic architecture.

Our Solution

  • Migrated from VB6 to .NET 8, eliminating outdated components and unlocking high-performance and scalable capabilities. 
  • Ensured full compatibility with modern development standards and regulatory frameworks.
  • Using AWS Lambda, the monolithic system was converted into microservices, increasing failure tolerance and modularity.
  • Enabled auto scaling, significantly reducing operational costs during non-peak hours.

Results

  • 80% Faster 
  • 60% Reduction via AWS Lambda Auto Scaling
  • 40% Boost in Speed
  • 3x Higher During Peak Load

CU Loan Source achieved faster performance and 3x scalability after modernizing its legacy infrastructure.
