Societe Generale, a multinational investment bank, adopted Apache Airflow® as part of their Open Banking transformation to transition from an ITIL model to a DevOps approach, emphasizing shared responsibility and developer autonomy. After evaluating various orchestration tools, they selected Apache Airflow® for its user-friendly interface, community support, and Python-based extensibility, which facilitated interactions with both private and public clouds, and supported standard ETL and ELT workflows. This shift resulted in significant license cost savings, accelerated development workflows, and the establishment of over 150 infrastructures. As a Product Owner, Alaeddine Maaoui highlighted the successful integration of open-source tools in mission-critical banking environments and emphasized the importance of selecting tools suited to specific use cases. Looking ahead, Societe Generale plans to upgrade from Airflow 1.X to 2.X with support from Astronomer, demonstrating their commitment to modernizing their data orchestration processes.
