Lorsque j'ai commencé à déployer du PHP, aux alentours de 2002, la mise en place de cache d'opcode, de reverse proxy pour assets statiques et de déploiement atomiques était encore rare et peu documentée. Le monde a évolué, PHP a beaucoup évolué et c'est l'occasion de faire le point sur les bonnes pratiques de déploiement PHP (en particulier sur une architecture cloud): - déploiement immutables - séparation code / données - cache opcode - séparation serveur HTTP / VM PHP - gestion des sessions - gestion des assets Le but de la présentation est de présenter (et de justifier, en les contextualisant) ces bonnes pratiques.
