en.Wedoany.com Reported - Brazil's Bradesco and Caixa Econômica Federal are driving the evolution of mainframe platforms toward hybrid architectures and intelligent capabilities, transforming them from centralized transaction cores into modern distributed platforms that support cloud, APIs, and artificial intelligence.
At Bradesco, the mainframe has long served as the core transaction platform, handling accounts, bank cards, and transfer operations, ensuring the execution of critical business logic with high consistency, integrity, and availability. According to the bank's Tech CIO Daniel Falbi, the fundamental role of the mainframe remains solid, as it still processes nearly 70% of global IT production workloads across 28 industries and over 70 countries, based on IBM data. The profound change lies in the direction of architectural evolution: Bradesco is shifting from a centralized, monolithic environment to a hybrid model integrating cloud, APIs, and digital channels. The mainframe is no longer an isolated structure but operates as a dynamic component within a broader ecosystem. Falbi noted that the mainframe has transformed into a long-term strategic platform oriented toward continuous innovation.
In Bradesco's current IT strategy, the mainframe not only serves as the foundational platform for critical applications and a core element of the hybrid architecture but also handles high-risk processes such as reconciliation and financial settlement. It acts as the transaction backbone and the golden source of enterprise data, ensuring the high reliability required for bank card and financial transfers. The mainframe is beginning to operate as a highly data-oriented and intelligent platform, integrating aggregation, distribution, and automation. Falbi reported that the bank is expanding the application of artificial intelligence in operations, system observability, development, and security, accompanied by ongoing advancements in AIOps for automation, integration with analytics platforms, and business impact-driven observability.
On the modernization path, Bradesco adopts an incremental, structured strategy aimed at creating full-stack value rather than replacing the mainframe. This strategy advances on three fronts: technology, software, and operations. On the technology front, the bank is undertaking continuous hardware upgrades to improve energy efficiency and sustainability, while consolidating physical facilities to reduce footprint. On the software and development front, the goal is to reduce dependency on specific vendors by integrating modern tools, adopting Git and market-standard IDEs, and scaling toward advanced pipeline CI/CD. On the operations front, the focus is on on-demand environment provisioning and large-scale automation, with data-driven operations featuring real-time telemetry and enhanced integration with the cloud ecosystem.
Regarding the future of the mainframe, Falbi emphasized that it will continue to serve as the foundation for business continuity, maintaining high availability and operating as the transaction backbone for critical systems. The fundamental difference lies in its new positioning as a platform for modern distributed architecture, operating transparently to users while connecting cloud, data, and artificial intelligence at scale. Based on this vision, Bradesco is moving toward a smarter, more efficient environment, with artificial intelligence as a horizontal layer, widespread operational automation, and business-oriented observability. Security will continue to be resilient by design, with future operations advancing in encryption and quantum-safe scenario preparation, integrating security from the outset and evolving toward EDR detection models and micro-segmentation.
At Caixa Econômica Federal, the mainframe also maintains a core role, handling accounts, transactions, and critical financial services. The bank stated that due to the industry's high reliability requirements, the mainframe processes the majority of financial transactions. Beyond traditional operations, it also supports social programs and seasonal high-volume business, serving as the bank's primary technical infrastructure. In a written response, Caixa explained that despite digital advancements, the mainframe remains crucial due to its security, performance, and availability. The bank noted that the trend is not replacement but continuous modernization of the mainframe, integrating it with hybrid architectures, cloud, APIs, and artificial intelligence. Although challenges exist in expert training, capacity building and automation initiatives are alleviating this situation. The mainframe thus remains strategically significant, evolving from an isolated model into an integrated ecosystem, serving as the reliable core of bank operations and a foundation for innovation.
