We're currently running 2 PHP monoliths. One for CH and another one for the EU. These monoliths result in bottlenecks by the fast-growing business. At some point, we decided to switch to a more flexible microservice architecture. Additionally, we want to use SAAS software if possible.
The whole migration should be done step by step and we want to start with a single market. Our System is partially live now and we're still working on it. But there is already so many learnings to talk about.
