Ansible Summary.md

Ansible

It's an automation language, engine and orchestration tool developed by Red hat written in Python using YAML format for writing instructional scripts, affectionately known as "Ansible playbook".

It has an automation engine that runs Ansible playbooks. Cloud provider is present in the ecosystem (AWS, Azure, Google, DigitalOcean, OVH, etc…).

Pros

  • It is an agent-less tools In most scenarios, it use ssh as a transport layer. In some way you can use it as 'bash on steroids'
  • It is very easy to start. If you are familiar with ssh concept - you already know Ansible (ALMOST).
