## Resource

Alexis "Horgix" Chotard, Staff Engineer chez PayFit, raconte comment cette licorne française de la paie a réduit sa facture AWS de 40% tout en continuant à croître. En 2020, l'infrastructure reposait sur un cluster Kubernetes auto-géré avec Kops. Trois ans plus tard, PayFit s'appuie sur Aurora, ElastiCache, OpenSearch, SQS, EventBridge et Lambda. Comment passer du self-hosted aux services managés sans big bang ? Quels principes directeurs ont guidé cette transformation ? Pourquoi assumer le vendor lock-in plutôt que de courir après le multi-cloud ? Alexis partage les coulisses techniques et humaines de cette migration progressive.
