Vous avez beau avoir modernisé vos applications, les avoir rendu stateless, 12factor-compliant, etc., si vous n'avez pas l'infrastructure pour les déployer proprement et les gérer, votre bénéfice final sera fortement amoindri. Cette conférence a pour but de vous faire ressortir avec une définition et une vision claires des principaux concepts qui caractérisent une infrastructure moderne. Nous y parlerons Configuration Management, infrastructure immuable, infra-as-Code, orchestration, self-healing, systèmes distribués, applications Cloud Native, Serverless ... et ce n'est qu'un avant goût !
