Compute4SBB I - Sovereign Cloud and Public Cloud

Service November 9, 2026 | Compute4SBB I is part of an overarching SBB procurement project. The project is technology-neutral: SBB is not committed to a single operating model or a single technology provider. Instead, it procures a comprehensive service portfolio. It covers different requirements for security, compliance, data sovereignty, innovation and economic efficiency. In addition, SBB's currently distributed data centers and computer rooms will be consolidated. The project consists of three procurement projects, which will be published at slightly different times: Compute4SBB I – Sovereign Cloud and Public Cloud Compute4SBB II – Data Center Compute4SBB III – Compute & Platform Services and Private Cloud Together, these services form a modular construction kit. From this, the platform that best suits your requirements can be selected for each application. The reason: Not all applications have the same requirements. Some benefit from the high speed of innovation, scalability and the wide range of services offered by the public cloud. Others need more control and controllability because of regulatory, data protection, business-critical or sovereignty-related requirements. Sovereign Cloud, Private Cloud and Data Center are available for them. SBB decides which application goes on which platform based on defined criteria. This includes the need for protection, data classification, regulatory requirements, availability, sovereignty as well as economic and technical aspects. The choice is not made across the board, but rather based on needs and understandable. The basis is a standardized assessment. Because all four operating models are procured in parallel, a suitable model is available for every application. High requirements for security, compliance, data sovereignty and digital sovereignty can also be met in this way. Dam
