DEVOPS - INFRASTRUCTURE AS CODE Ansible Tool di configurazione di risorse (ad esempio di macchine virtuali in VMware) Terraform Orchestratore di risorse: permettere di definire in modo dichiarativo le risorse fornite da una infrastruttura on premise come Vmware oppure in cloud come AWS o GCE Kubernetes Orchestratore di container
