Intesa Sanpaolo Completes Core Banking Shift to Google Cloud

The migration, part of a multi-billion-euro overhaul, involved moving more than 800 applications to Google Cloud regions in Turin and Milan. By decommissioning an equal number of legacy systems housed at its headquarters, the bank aims to resolve the technical debt accumulated through years of mergers and acquisitions. Intesa utilized its digital subsidiary, Isybank, as a pilot project to test the infrastructure before committing to the full-scale shift.

This move addresses concerns from the European Central Bank, which has frequently cautioned that reliance on fragmented, outdated software stacks creates significant cyber and operational vulnerabilities. According to a joint statement from Intesa, Google Cloud, and TIM, the transfer of massive datasets occurred without major incidents or service interruptions, maintaining high security standards and low latency. Intesa now joins peers like Santander, BBVA, and Lloyds in navigating the complex transition away from legacy mainframes to more flexible, scalable cloud environments.
