Ansible Has a Free Automation Tool — Configure Servers, Deploy Apps, and Manage Infrastructure Without Agents

SSH into server. Run apt update. Install nginx. Copy config. Restart service. Repeat for 10 servers. Miss one step on server #7. Debug for an hour. Ansible automates all of it. Write a YAML playbook once, run it against 100 servers. Idempotent — run it twice, nothing breaks. No agent to install on servers.
