Why did you choose Ansible over Puppet? What are their differences?

Ansible and Puppet are both configuration management tools, but they have fundamental differences that influence the choice.

Why choose Ansible:

• Simplicity and ease of learning. Ansible uses YAML to describe tasks, making playbooks intuitive.
• Agentless. Ansible operates over SSH without needing to install additional software on managed nodes, simplifying deployment.
• Imperative approach. Ansible allows describing execution steps, which can be more convenient for complex scenarios.

Main differences between Ansible and Puppet:

• Operating model: Puppet is declarative, describing the desired state, and Puppet ensures the system reaches it. Ansible is imperative, describing a sequence of actions.
• Agents: Puppet requires installing an agent on target machines, while Ansible does not.
• Description language: Puppet uses its own DSL, Ansible uses YAML + Jinja2.
• Architecture: Puppet uses a master-agent model, Ansible uses a push model over SSH.

The choice depends on project requirements, infrastructure, and team preferences.
