This document discusses Christian Deger's talk on building microservices in the cloud. It describes how Autoscout24 migrated from a monolithic architecture running on 2,000 servers in their own data centers to a microservices architecture running on AWS. Key aspects of the migration included moving from .NET to Java, adopting a self-contained systems approach where autonomous teams own their microservices end-to-end, implementing continuous delivery practices, and shifting to a more collaborative culture between development and operations teams. The new architecture aims to reduce time to market, be mobile-first, support data-driven decisions, keep services loosely coupled, and emphasize infrastructure as code.
