## What is BNP Paribas's technology stack?

BNP Paribas runs most of its technology in data centers it owns and brings cloud vendors inside them. IBM Cloud has been hosted in the bank's data centers since 2019; on April 29, 2025 the partnership was renewed for 10 years, with a new dedicated area planned for 2028 and GPUs on IBM Cloud for generative AI. In January 2025 the bank adopted Oracle Exadata Cloud@Customer for its on-premises databases and said it has not placed any client data or production environments containing sensitive data in the public cloud. Core banking applications run on IBM Z, according to an IBM case study, and new applications are built on containers with Red Hat OpenShift. The AI layer is the internal LLM as a Service platform, deployed in June 2025 on GPU infrastructure in the Group's data centers, serving open-source models and Mistral AI models; Mistral AI was renewed for three years in May 2026. A five-year Google Cloud partnership signed on September 24, 2026 adds Gemini models and Gemini Enterprise under what Group CIO Marc Camus calls a multi-cloud and multi-model approach.

## What are the layers of BNP Paribas's technology stack?

## Who runs technology at BNP Paribas and what is the cloud plan?

Marc Camus, previously CIO of BNP Paribas Fortis, has been Group Chief Information Officer since 1 April 2025. He succeeded Bernard Gavgani, sits on the Executive Committee and reports to Chief Operating Officer Philippe Maillard. ([BNP Paribas](https://group.bnpparibas/en/press-release/bnp-paribas-marc-camus-is-appointed-group-chief-information-officer))

The cloud plan is to move workloads into the dedicated IBM Cloud zone rather than out to a public region. Christophe Boulangé, chief technology officer for cloud, told American Banker in April 2025 that the bank plans to move nearly half its applications to a dedicated IBM Cloud environment within its data centers by December 2026, that the zone will serve as a disaster-recovery site for critical applications such as payment systems, and that IBM's 'keep your own key' encryption was a factor in the choice. ([American Banker](https://www.americanbanker.com/news/bnp-paribas-expands-partnership-with-ibm-cloud))

For AI, Group CTO Jean-Michel Garcia described in May 2026 a group-level framework with federated governance by business and function, connected through an internal AI factory and the LLM as a Service platform, with nearly 1,000 AI use cases underway. Camus has said a multi-cloud and multi-model approach lets the bank choose 'the right model, infrastructure and level of control' for each case. ([SiliconANGLE](https://siliconangle.com/2026/05/20/hybrid-ai-governance-now-critical-european-banking-ibmthink), [BNP Paribas](https://group.bnpparibas/en/press-release/bnp-paribas-and-google-cloud-announce-new-partnership-on-agentic-ai-and-cloud-innovation))

For 2026 Camus names agentic AI as the investment area and three priorities for the technology function: service continuity, security and cost control.

## Common questions

### Does BNP Paribas use the public cloud?

Only within limits it has stated. In January 2025 the bank said it has not placed any client data or production environments containing sensitive data in the public cloud, and that it invests in private and dedicated cloud inside data centers it owns. The September 2026 Google Cloud agreement is described as strengthening a multi-cloud approach within its existing security and data governance framework.

### Which cloud providers does BNP Paribas work with?

IBM Cloud, hosted inside BNP Paribas data centers since 2019 and renewed for 10 years in April 2025; Oracle, whose Exadata Cloud@Customer runs the bank's Oracle databases on premises; and Google Cloud, under a five-year partnership announced on September 24, 2026 that covers AI-optimized infrastructure, Gemini models and Gemini Enterprise.

### What does BNP Paribas's core banking run on?

On the IBM Z mainframe platform, according to an IBM case study, which says the bank runs its strategic core banking applications and databases exclusively on IBM Z and has modernized the development environment with IBM Developer for z/OS and Git. Newer applications are built with containers on Red Hat OpenShift.

### Which AI models does BNP Paribas run?

A mix. The internal LLM as a Service platform, deployed in June 2025 on GPUs in the Group's own data centers, serves open-source models and Mistral AI models, with models trained on internal data to follow. The 2026 Google Cloud partnership adds Gemini models, starting with the corporate and institutional bank's LLM@CIB assistant.

### Who is BNP Paribas's chief information officer?

Marc Camus, who took the role on 1 April 2025 after leading IT at BNP Paribas Fortis. He succeeded Bernard Gavgani, sits on the Group Executive Committee and reports to Chief Operating Officer Philippe Maillard. Jean-Michel Garcia is Group CTO.
