What is Ansible?
Ansible is an open-source software provisioning, configuration management, and application deployment tool. It enables infrastructure as code (IaC), allowing users to define and manage infrastructure and applications through a human-readable configuration file. Ansible is designed to be simple, efficient, and scalable, making it a popular choice among DevOps teams and system administrators.
Main Features
Ansible’s main features include:
- Agentless architecture: Ansible doesn’t require any agents to be installed on the target machines, making it easy to manage and maintain.
- Playbooks: Ansible playbooks are YAML files that define the desired state of the infrastructure and applications.
- Modules: Ansible has a vast collection of modules that can be used to perform various tasks, such as managing users, installing packages, and configuring networks.
