What is Ansible?

Ansible is an open-source automation tool that helps users manage and configure infrastructure, applications, and services. It provides a simple and efficient way to automate repetitive tasks, deploy software, and manage configuration changes across multiple environments. Ansible uses a modular design and is built on top of Python, making it easy to extend and customize.

Main Features of Ansible

Ansible has several key features that make it a popular choice for automation and configuration management. Some of the main features include:

• Agentless architecture: Ansible does not require any agents to be installed on the target machines, making it easy to manage infrastructure without adding additional overhead.
• Playbooks: Ansible playbooks are YAML files that define the automation tasks and workflows. They are easy to read and write, and can be reused across multiple environments.
• Modules: Ansible has a large collection of modules that can be used to perform specific tasks, such as managing users, installing software, and configuring networks.

Ansible Snapshot and Restore Workflow

What is a Snapshot?

In Ansible, a snapshot is a point-in-time capture of the current state of the infrastructure or application. Snapshots can be used to track changes, roll back to a previous state, or create a baseline for future changes.

How to Create a Snapshot

Here are the steps to create a snapshot in Ansible:

1. Create a new playbook: Create a new playbook that defines the snapshot task.
2. Use the snapshot module: Use the snapshot module to create a snapshot of the current state.
3. Save the snapshot: Save the snapshot to a file or database for future reference.
