Munich Dumps Microsoft for Open Source, Saving €1.5 Million a Year

Munich, Germany's third-largest city, is making a major move to cut software costs by replacing proprietary programs with open-source alternatives. The city plans to swap VMware with Proxmox, Jira and Confluence with OpenProject and XWiki, and Oracle databases with PostgreSQL. These changes are expected to save at least €1.5 million (about $1.6 million) every year. This isn't Munich's first try at open source—back in 2003, the city famously migrated 14,800 desktops to Linux, saving €11 million, but switched back to Windows in 2017 due to political pressure, not technical problems.

So why is this time different? Instead of focusing on desktop Linux, Munich is targeting the invisible infrastructure that powers city services. By replacing expensive licenses with free software, the city gains more control and can share improvements with other municipalities. The savings come from avoiding costly subscriptions and licensing fees. For example, switching from VMware to Proxmox alone can cut virtualization costs significantly. The city's chief digital officer, Dr. Laura Dornheim, emphasized that open source succeeds when it aligns with political priorities like budgets and public services.

For everyday residents, this means more money for other city services or lower taxes. It also sets an example for other governments: open source isn't just about ideology; it's a smart financial move. However, there's a catch: open-source software requires in-house expertise to maintain, and migrations can be complex. Munich's earlier Linux desktop project struggled with compatibility and user expectations, showing that careful planning is key. But this time, the city is taking a pragmatic, layer-by-layer approach, which is more likely to stick.

Ultimately, Munich's strategy could inspire other cities to follow suit, reducing their reliance on big tech vendors and keeping more taxpayer money local. As digital sovereignty becomes a bigger concern, especially with cloud services, open source offers a way to maintain control over data and infrastructure. While the savings are significant, the real win might be the message: open source is a viable, cost-effective alternative for public institutions.
