Munich shifts infrastructure to open source software, skipping Linux desktop return

Munich is replacing proprietary infrastructure software with open-source alternatives, according to Dr. Laura Dornheim, the city’s chief digital officer. She outlined this strategy during a keynote at Open Source Summit Europe, clarifying that the city is not returning to its previous Linux desktop deployment.

The migration involves swapping VMware for Proxmox and replacing Jira and Confluence with OpenProject and XWiki. Munich is also adopting PostgreSQL as an alternative to Oracle databases. These infrastructure and collaboration shifts are expected to save the city roughly €1.5 million annually.

Political alignment drives strategy

Dornheim stated that open-source initiatives in the public sector often fail due to political misalignment rather than technical issues. Munich abandoned its LiMux Linux desktop project over a decade ago after a new government secured a deal making Munich the headquarters for Microsoft Germany.

The original LiMux rollout began in earnest in 2006, following a 2003 council vote to migrate from Windows NT 4.0. Dornheim noted that the project’s end was not caused by technical shortcomings. Instead, the lack of durable political support proved fatal for the desktop initiative.

Current approach focuses on infrastructure

The city’s current strategy differs from its first Linux campaign by avoiding a wholesale desktop resurrection. Instead of making Linux the central focus, Munich is replacing individual layers of proprietary infrastructure where practical benefits are clear. This targeted approach allows the city to build software for its own needs and for other municipalities.

Dornheim emphasized that technical capability alone is insufficient for public-sector open-source adoption. Projects must align with political agendas to survive. By focusing on backend infrastructure rather than user-facing desktops, Munich aims to secure the political support necessary for long-term success.

What should you do?

Organizations considering similar migrations should evaluate their political and organizational support structures before initiating large-scale open-source projects. Assessing the total cost of ownership for infrastructure replacements can reveal significant savings opportunities. Monitoring vendor lock-in risks in proprietary suites may also prompt timely transitions to open-source alternatives.

What to do and how to stay safe: Munich

• Audit current proprietary infrastructure contracts to identify potential migration targets and cost savings.
• Ensure internal political and executive support aligns with open-source adoption goals before proceeding.
• Evaluate open-source alternatives for specific infrastructure layers rather than attempting full desktop replacements.
• Monitor vendor support lifecycles to anticipate necessary migrations before end-of-life dates approach.
