During this talk I will tell you a real story from the trenches about a product my team and I created from scratch adopting a microservices based architecture. I will share with you some insights on the final architecture, the issues we faced (both at a technical and organizational level) and how we tried to solve them using best practices and some tools provided as free software by the community.

9. We were happy for the partial success, but we had still a
lot of work to be done…
