Ansible Contd

• Ansible is widely adopted for
  • Configuration Management
  • Network Automation
  • Administrative Activity Automation.

How Ansible Works

• Basic Illustration
  
• Ansible should be installed on the control node which comes with inbuilt python or uses the existing python on the control node
• On the Nodes, we need to ensure python is installed.
• When we execute Ansible Playbook, Ansible control node logs in into nodes parallely (by default 5) and executes the playbook using python
• To login into the node Ansible needs credentials configured.
• Protocol used for logging into
• Linux Machine: SSH
• Windows Machine: WinRM
