Santander CIB Migrates to Digital Banking Platform Gravity, to Benefit From Cloud Tech

With the importance of digital banking continuing to establish itself in the modern world, Banco Santander has migrated its corporate and investment banking business (Santander CIB) to its new digital banking platform, Gravity

The bank has successfully migrated all commercial customers in the UK and the consumer business in Chile without any service interruption. Santander CIB, which supports corporate and institutional clients, has used the Gravity platform to migrate to Google Cloud. There, it manages more than a million accounting operations and half a million treasury operations per day.

Dirk Marzluf, chief operating and technology officer at Banco Santander, said: “Innovation is at the heart of our transformation, helping us serve customers better while delivering profitable growth and value creation. The Gravity banking platform, and other examples across the group, are testament to this. The Santander CIB migration to the cloud is a new milestone in the group’s transformation towards a simpler, more integrated model, contributing to enhanced profitability.”

Moving to the cloud

Gravity, the bank’s software and cloud-native core banking platform, enables Santander to deploy on both private and public clouds. Santander plans to migrate the vast majority of its core banking worldwide to the Gravity platform by the end of 2024, mostly in its private cloud.

Santander has in-house software that digitises core banking, the most critical part of a bank’s IT infrastructure. This transformation is allowing easier and faster access to data, more simplicity and faster time-to-market. Additionally, it makes it possible to deliver new capabilities for customers in hours, instead of weeks, and more frequent app updates.

The bank is also able to greatly improve its customer experience, products and services, and drive value using real-time analytics. This change is also bringing significant efficiencies through cutting-edge end-to-end automation and other savings.

Santander’s core banking digital journey started in 2022 and the vast majority will be completed at the end of 2024. Apart from the UK, Chile and Santander CIB, the transition is well advanced in Brazil. At the completion of the programme, more than one trillion technical executions will be managed every year by the Gravity platform within Santander’s systems.

Simultaneous benefits

The Gravity software allows parallel processing, meaning the bank can simultaneously run workloads on its existing core banking mainframe and in the cloud. This allows it to perform real-time testing with no disruption to its businesses. Once satisfied with the stability and performance, the bank can then transition from the mainframe system to the cloud.

These same capabilities are available globally to other companies in all industries with Dual Run by Google Cloud, a mainframe migration service that simplifies the transition from legacy mainframe systems to the cloud. Based on Santander’s Gravity technology, Dual Run has been further developed by Google Cloud’s engineers to encompass more use cases and optimise for Google Cloud.

Santander’s successful cloud-native core banking platform is built upon the knowledge transfer of a large team of IT professionals. Some of whom created the legacy system 20 years ago and are now moving it to the cloud, as well as young developers and engineers.

This gives Santander’s 16,500 software developers and engineers a modern, high-performing environment to create customer-centric applications and increase the bank’s ability to attract top talent. Santander has also reduced the bank’s energy consumption from its IT infrastructure by 70 per cent, contributing to its responsible banking targets.
