3.1 In general

3. Current Open Source projects

We are already actively implementing a wide range of projects using Open Source systems. This continuously strengthens the digital infrastructure of the City of Vienna, drives current developments forward, and deliberately promotes digital sovereignty. A look into our data center shows the distribution: 3,000 Windows servers and 2,300 Linux servers (including 1,900 Red Hat Enterprise Linux, 200 SUSE Linux Enterprise Server, and 200 Oracle Linux) are currently in use. The trend is increasingly moving toward Linux in the data center.
