Overview
Ansible is known for its simplicity and agentless architecture. It uses YAML-based 'Playbooks' to define automation tasks. Unlike Terraform, which focuses on provisioning infrastructure, Ansible is often used for configuring the software and settings inside the virtual machines or containers.
Key Features
- Agentless: Communicates with target machines over SSH or WinRM, requiring no software installation on the targets.
- Idempotent: Ensures that tasks only make changes if the current state does not match the desired state.
- Extensible: Features a large library of modules for managing everything from Linux packages to cloud resources.
- Human-Readable: Playbooks are easy to read and write, even for those without deep programming experience.
Use Cases
- Patching and updating servers.
- Deploying application code.
- Orchestrating complex multi-tier deployments.
