What is Deutsche Bank's technology stack?
Deutsche Bank's technology stack is a hybrid built around Google Cloud. The bank chose the public cloud in 2019 and signed its strategic partnership in December 2020; by February 2025 it had moved around 260 applications to Google Cloud, including its SAP S4/HANA finance platforms (17 financial reporting systems) and its strategic risk management system. In German retail banking, Deutsche Bank and Postbank were consolidated onto one platform, and a unified online and mobile banking platform on Google Cloud serves around 19 million clients since August 2025, with Spanner as its database. What stays in the bank's own data centers runs largely on Oracle: a 2021 agreement moves the bulk of its Oracle Database estate to Exadata Cloud@Customer, with 10,000 Oracle Databases planned overall, and Kyndryl operates the Continental European core banking infrastructure. AI sits on the cloud layer: Vertex AI and Gemini models, the dbLumina assistant on Gemini 2.5 Pro, and GitHub Copilot and Gemini Code Assist for over 15,000 developers. Marie-Jeanne Deverdun has led the Technology, Data and Innovation division since May 1, 2026.[1][2][3][4][5][6][7][8][9]

Who runs technology at Deutsche Bank and where are its engineers?
Technology sits in the Technology, Data and Innovation (TDI) division. Marie-Jeanne Deverdun, previously Chief Operating Officer for the Corporate Bank and Investment Bank, joined the Management Board as Chief Technology, Data and Innovation Officer effective May 1, 2026, succeeding Bernd Leukert, who left when his contract expired at the end of June.[9]
Reuters reported in June 2026 that the bank has around 9,000 employees in its technology function in India, about 45% of its global tech workforce. The bank's technology page names Berlin and Cary among its technology hubs, and Leukert wrote in February 2025 that a Cloud Engineer Program built with Google Cloud had trained more than 6,000 employees in cloud and AI skills.[15][3][1]
The design is hybrid on purpose. Oracle's 2021 release says Exadata Cloud@Customer is for applications that either will not move to the public cloud or may do so in the future, and Rhino said in 2026 that what remains outside Google Cloud in the private bank is mostly a matter of sovereignty and regulatory restrictions in places such as Switzerland and Singapore. On AI the technology page says: 'We place great emphasis on remaining independent from individual providers or models'.[2][10][3]
Engineers work under a token budget: Denis Roux, chief information officer of the investment bank, told Reuters that engineers are allocated quotas for tokens and can request additional capacity but have to demonstrate value.[15]

Which cloud provider does Deutsche Bank use?
Google Cloud is the strategic public cloud partner, under a partnership set up in December 2020. By February 2025 the bank had moved around 260 applications there, including its SAP finance platforms, and the German retail online and mobile banking platform runs on Google Cloud. Databases that stay on premises run on Oracle Exadata Cloud@Customer in the bank's own data centers.
What does Deutsche Bank's retail banking run on?
A single platform for the Deutsche Bank, Postbank and Norisbank brands. The Postbank migration moved roughly 19 million product contracts and the data of 12 million customers onto Deutsche Bank's systems, and the unified online and mobile banking platform on Google Cloud, with Spanner as its database, completed its rollout to around 19 million clients in August 2025.
Which AI models does Deutsche Bank use?
Mainly Google's. The Google Cloud partnership gives the bank Vertex AI and Gemini models, and Finextra reported in February 2026 that the dbLumina assistant runs on Gemini 2.5 Pro. The bank also says it wants to stay independent from individual providers or models, and its developers use both GitHub Copilot and Gemini Code Assist.
Who is Deutsche Bank's technology chief?
Marie-Jeanne Deverdun, Chief Technology, Data and Innovation Officer and a Management Board member since May 1, 2026. She was previously Chief Operating Officer for the Corporate Bank and Investment Bank and succeeded Bernd Leukert, who led the division from 2019 and left at the end of June 2026.
Does Deutsche Bank still run mainframes and its own data centers?
Yes, in part. The private bank's CIO said in September 2026 that mainframes in Spain, Italy, Germany and Belgium were being moved to a cloud architecture, Oracle's Exadata Cloud@Customer runs in the bank's own data centers, and Kyndryl operates the Continental European core banking infrastructure under a contract extended in 2022.
