# Munich Shifts Strategy to Open-Source Infrastructure Over Linux Desktops The city prioritizes modular open-source infrastructure to ensure long-term political and financial sustainability. - **Source:** [Latest news](https://brifing.si/source/77d15218-219f-472d-bf40-31b5646d2942) - **Published:** 2026-10-16 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/c52bf056-1f85-479d-b6aa-ba08c53d5d5d ## Strategic Shift in Munich Munich is pivoting its digital strategy by replacing proprietary infrastructure with open-source alternatives. Unlike the previous LiMux project, which focused on Linux desktops, the current approach targets specific backend layers. Dr. Laura Dornheim, the city's chief digital officer, emphasizes that this modular strategy avoids the political volatility that previously derailed large-scale desktop migrations. ## Infrastructure Replacement Targets The city is actively migrating core services to open-source platforms to reduce dependency on proprietary vendors. Key transitions include replacing VMware with Proxmox, moving from Jira and Confluence to OpenProject and XWiki, and adopting PostgreSQL to replace Oracle databases. These infrastructure changes are projected to save the city approximately €1.5 million annually. ## Lessons from LiMux History Between 2003 and 2013, Munich operated over 14,800 Linux desktops under the LiMux project. Despite technical successes and €11 million in savings, political shifts led to a reversal in 2017. The city learned that technical capability alone is insufficient; long-term success requires durable political support and alignment with broader government agendas. ## Political Drivers of Change The previous move away from Linux was driven by political pressure rather than technical failure. A new government administration prioritized hosting Microsoft Germany's headquarters, leading to a full return to Windows. Current leadership now frames open-source adoption through tangible benefits like budget savings and public service improvements to maintain consistent political backing. ## Digital Sovereignty and Compliance Digital sovereignty has become a critical technical and political issue for the city. Concerns regarding GDPR compliance during potential cloud transitions to Azure influenced the decision to scrutinize proprietary tools. By managing its own infrastructure, Munich gains greater control over data and reduces the management overhead associated with external vendor compliance requirements. ## Public Money, Public Code Munich has officially embraced the principle that software developed with public funding should be available for others to use. The city established an Open Source Program Office in 2024 to coordinate these efforts. This structure ensures that software developed by the city can be inspected, improved, and reused by other municipalities. ## Collaborative Software Ecosystems The city is moving beyond being a mere customer of software licenses to becoming an active participant in development. Applications like DAVe, used for traffic data analysis, are already being shared with other cities like Wolfsburg. Additionally, the city has launched MUCGPT, an internal AI tool, to assist employees with administrative tasks. ## Future Sustainability Outlook By focusing on modular infrastructure rather than a single operating system, Munich aims to create a sustainable model for public sector IT. The city's Open Source Sabbatical program further supports this by funding developers. This multifaceted approach ensures that open-source adoption remains resilient against future political changes while delivering consistent financial returns. ## Sources covering this story - https://www.zdnet.com/business/munich-proprietary-open-source-no-linux-desktop/ — --- _Summary written by Brifing from the original reporting.
