Core System Upgrade Project for a National Joint-Stock Commercial Bank
To support its business growth, the bank initiated a next-generation core banking system transformation project, drawing on distributed architecture design concepts from the internet industry. This effort involves a comprehensive upgrade of both the deployment and application architecture of the core banking system.
- 01
The direct bank is positioned to operate independently in the future, requiring its own standalone account and payment systems.
- 02
From a technical perspective, it is necessary to decouple the account and payment systems from the existing core system.
The Solution Includes the Following Measures:
A distributed financial cloud platform was built to support core functionalities such as customer management, product factory, deposit management, and card management. The platform is capable of serving a massive customer base, handling sudden spikes in transaction volume, and supporting large-scale data processing, meeting the demands of interest rate liberalization and internet-driven banking scenarios.
Daily transaction volume reached 200 million, scalable to 300 million with future expansion;
Supports ultra-large-scale business concurrency, with TPS exceeding 10,000;
Eliminated single points of failure—system remains available even during partial hardware failures;
Enables unified product management and analytics with a consolidated product parameter view;
Effectively addresses concurrency for hotspot accounts;
Significantly enhances disaster recovery capabilities.
