Ansible

1. Infrastructure as Code (IaC): Ansible treats infrastructure as code, allowing you to describe your desired state in declarative YAML files called playbooks.
2. Playbooks: Playbooks are sequences of tasks that define the steps to configure, manage, and deploy resources and applications.
3. Inventory: Ansible uses an inventory file to define the target hosts or systems on which tasks should be executed.
4. Modules: Ansible provides a wide range of built-in modules to perform various tasks, such as installing software, managing files, interacting with cloud services, and more.
5. Ad-Hoc Commands: Ansible enables you to execute single tasks on remote systems using ad-hoc commands, useful for quick configuration changes.
6. Idempotence: Ansible is idempotent, meaning that applying the same configuration multiple times has the same result as applying it once. This ensures consistent and predictable outcomes.
7. Agentless: Ansible does not require agents to be installed on remote hosts; it uses SSH for communication, making it lightweight and easy to manage.
8. Roles: Roles are a way to organize and encapsulate playbooks and tasks for reuse across different projects.
9. Configuration Management: Ansible can be used for configuration management, ensuring that systems are configured consistently and in compliance with desired standards.
10. Orchestration: Ansible can orchestrate complex workflows involving multiple systems and applications.

Ansible simplifies and accelerates IT operations by automating repetitive tasks, reducing human error, and promoting collaboration between teams. It is commonly used for infrastructure provisioning, application deployment, configuration management, and other automation needs.
