DeliveryHero Holding GmbH, IT System Operations, Berlin, Germany

The platform was originally designed by different owners, but there was an ownership transfer and now it is maintained by us. It has always been based on Debian.

We love Debian because of its flexibility, ease of maintenance and the fact that there are lots of available software which pass through internal Q&A. Also, it is free of vendors' restrictions. The number of workstations/servers are ~30/400 including physical and virtual machines.
