The AutoScout24 Technology Change - crazy or trendsetting?

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.

Are we out of our minds?
Are our employees running away screaming?
What strategic decisions have motivated us?
How do we keep up operation and product development?
What is our approach and what have we learned so far?
