AutoScout24 is a pan-European vehicle marketplace with 10 million users. We are currently turning our IT inside out: from Windows and .NET to Linux and the JVM, from our own data centers to Amazon Web Services, from a monolithic architecture to microservices and from separate development and operations departments to "Your build it - you run it" teams. On the way, we are rebuilding the better part of our platform from scratch.
