Core Viewpoint - The Agricultural Development Bank of China is initiating a significant transformation of its technology architecture by launching the "Rebirth Project" in 2024, focusing on a distributed core system to enhance scalability, cost control, and system management capabilities [1][2]. Group 1: Challenges of Traditional Architecture - The centralized architecture has become a bottleneck for sustainable development, with insufficient resilience to meet financial continuity requirements [2]. - High costs associated with traditional technology solutions lead to a structural imbalance of "high input, low output" due to low resource utilization [2]. - The closed ecosystem of the centralized architecture restricts technological development and innovation, posing long-term risks [3]. Group 2: Blueprint for New Digital Foundation - The new digital foundation aims to ensure data security through multi-replica strong consistency mechanisms, achieving zero data loss and rapid recovery [5]. - Efficient resource management will be enabled through cloud-native technologies, allowing for elastic supply of computing resources and on-demand storage capacity [6]. - The new architecture aims to control costs by leveraging distributed technology to reduce operational expenses and resource waste [7]. - The focus on technological independence and open ecosystems will mitigate risks associated with reliance on imported technologies [8]. Group 3: Selection of Distributed Database - The chosen distributed database features a native distributed design that supports decoupling of applications and data, capable of handling PB-level data storage and high transaction processing [11]. - It ensures financial-grade reliability and data security through strong consistency mechanisms, achieving zero data loss during single-point failures [12]. - The cloud-native architecture allows for independent scaling of compute and storage resources, enhancing cost efficiency [13]. - The database is compatible with domestic chips and operating systems, supporting open-source protocols and avoiding technology black-box risks [14]. Group 4: Implementation Path for Distributed Architecture - The bank has developed an innovative "5+3+3+1" architecture for high availability, marking a significant advancement in the evolution of financial core systems [15][17]. - The five-replica main cluster serves as a "financial-grade ballast," ensuring business continuity even during regional failures [18]. - The three-replica escape cluster acts as a "second heart," capable of taking over core business functions in extreme scenarios [19]. - The three-replica remote cluster provides real-time disaster recovery capabilities, evolving from a backup plan to a real-time guarantee [20]. - An independent backup replica serves as a "time vault," protecting against operational errors and cyber threats [21]. Group 5: Achievements from Architectural Transformation - The new distributed architecture has significantly improved system performance, processing over 50 million transactions with a 100% success rate and enhancing overall processing capacity by nearly ten times [22]. - Resource utilization remains stable at over 65%, with the ability to scale up during peak traffic [22]. - The migration process was smooth and efficient, maintaining high compatibility with existing applications and enabling a comprehensive digital transformation [23][24]. Group 6: Insights on Digital Transformation in Finance - The successful launch of the new system in 2024 marks a significant milestone in the bank's technological upgrade, addressing previous architectural pain points and establishing a reusable upgrade path [25]. - The transformation illustrates that financial technology evolution is not merely a technical replacement but a comprehensive restructuring of capabilities [25].
