Consorsbank wanted to create the next generation consumer retail banking mobile application. Where most retail bank applications give customers the ability to check account balances, transfer balances and make payments, Consorsbank wanted its application to go further. With Diffusion, Consorsbank was able to; meet customer demand by delivering a fully functional, high performance and scalable mobile application, Simplify and speed retail banking application development, and provide a single communication solution for the bank’s customers.
Optimized network payload and streaming efficiency for all mobile and web apps.
Real-time financial data delivery ensures accurate, live account updates.
Scalable architecture serving millions with real-time updates and zero latency issues.
Consorsbank’s team objective was to deliver far more than the typical mobile retail banking applications provided to their valued customers. The digital bank wanted their mobile application to be the central point for managing, interacting with and tracking all the activities across each customer’s accounts. Consorsbank required a data platform that would isolate the bank’s existing back-end systems from the load generated by tens of thousands of mobile clients. Lastly, Consorsbank wanted to simplify application development and improve performance. Their existing application used different APIs for each of the back-end systems with which it interacted. This resulted in a low-performance application.
They wanted to give customers the ability to:
Many organisations must build business applications that can easily scale and run optimally over the Internet. To deliver a reliable, resilient, and high-performance application. Development teams must address the challenging unknowns of the Internet including the speed and quality of the network, load on the network, time to send the data to back-end servers, time to process/ distribute/store data on the back end, high and variable volume of users etc.
Consorsbank’s requirements were to overcome these unknowns in the simplest manner possible in order highly to deliver data in a scalable, efficient and reliable way so their customers receive the optimal mobile experience.
Consorsbank knew of DiffusionData through another BNP Paribas subsidiary, DAB bank. Consorsbank’s sister bank had addressed their application data challenges with the Diffusion Intelligent Event-Data Platform. As a result, Consorsbank elected to evaluate the Diffusion Platform to address their requirements and simplify and speed up their application development.
As part of the evaluation, Consorsbank performed a side-by-side comparison of two versions of its application, one used DiffusionData’s Diffusion framework and the other used traditional Request/Response messaging. Diffusion won the comparison test by delivering superior user experience, increased performance, faster response times, and reduced network payload due to the platform’s state-of-the-art data optimisation and communication technology. The decision was made.
With DiffusionData’s Data Distribution Framework, Consorsbank quickly developed their high-performance, event-driven mobile banking application. They delivered a new application experience to their customers that reacts in real-time to business events using a simple consistent API that spans all customer devices. The result is business growth and satisfied customers. An important ongoing benefit of the Diffusion platform is that whenever Consorsbank adds, modifies, or replaces a back-end system, Diffusion minimises the impact of changes on the application, speeding support of new functionality and devices.
Today, Consorsbank uses the Diffusion platform for its world-class mobile banking and trading application which runs seamlessly on the full range of mobile devices. The bank also plans to use Diffusion across the organization for other internal and external projects.
