What is Ansible?
Ansible is an open-source automation tool that helps IT teams manage and deploy software applications. It uses a simple, agentless architecture to automate tasks, making it a popular choice for DevOps and continuous integration/continuous deployment (CI/CD) pipelines. With Ansible, teams can define infrastructure and application configurations in a human-readable format, making it easier to manage complex environments.
Main Features of Ansible
Ansible offers several key features that make it an attractive choice for automation:
- Agentless Architecture: Ansible doesn’t require agents to be installed on target machines, making it easier to manage and deploy applications.
- Human-Readable Format: Ansible uses YAML or JSON files to define configurations, making it easy for teams to read and understand.
- Modular Design: Ansible’s modular design allows teams to break down complex tasks into smaller, reusable components.
