Même si la classification IaaS vs. PaaS est quelque peu éculée elle nous permettra de comprendre, en utilisant la plate-forme Cloud de Google, la répartition des responsabilités de Monitoring et de Management entre utilisateur et fournisseur de Cloud. Entre administration et monitoring de machines virtuelles, orchestration de service de load balancing, gestion de (base de) données, update transparent de stack technique et A/B testing nous allons parcourir les plus et les moins des approches orientées infrastructure et plate-forme tout en terminant sur une approche qui tente de combiner le meilleur des deux mondes
