Managing Infrastructure with Python, Fabric and Ansible
summary
Infrastructure moves from manual SSH sessions to declarative automation: don't SSH into machines, use tools and standardize lifecycle steps (provision → config → deploy). Fabric is shown as a quick Python-driven command runner but Fabric: simple but brittle when commands fail; Ansible is used for production work with inventories (including dynamic AWS), Ansible: roles, modules, templates to make git checkouts, service config and templated configs idempotent and auditable. Examples include a fabric fabfile, an Ansible inventory/playbook/roles layout and using the git module instead of raw shell commands.
