Ansible is a radically simple IT automation engine that simplifies cloud computing, configuration management, program setup, intra-service orchestration, and several other IT needs. Ansible uses a very simple language (YAML, in the form of Ansible Playbooks) that allow you to spell out your automation jobs in a way that means plain English. Using Ansible you can control multi host or device simultaneously using single command. You don’t need install client in apparatus or each server.
