Everyone talks about microservices' benefits. Almost nobody warns you about the side effects. This talk covers the unknown costs of microservices architecture through real experiences from failed and successful implementations: distributed data headaches, operational overhead, team topology mismatches, and the monolith you should sometimes keep. You'll leave knowing when to embrace microservices and when to run away.

45 min talk. Delivered at Alpes Craft 2023 (Grenoble, France). Available in French and English. Target audience: intermediate developers, architects, tech leads.
