Architecture
Controller - central system where playbooks run
Managed nodes - target servers/devices (agentless)
Inventory - static or dynamic host lists
Modules - perform tasks on nodes
Plugins - extend functionality (connection, callback, filter, etc.)
Rendering Model
Playbook -> Controller executes tasks -> Modules run on nodes -> Changes applied idempotently
Architectural Patterns

Frequently Asked Questions about Ansible
What is Ansible?
Ansible is an open-source automation tool for IT orchestration, configuration management, application deployment, and infrastructure as code. It uses simple YAML-based playbooks to automate complex IT workflows.
What are the primary use cases for Ansible?
Provisioning cloud infrastructure. Automating server configuration. Deploying applications and updates. Network device configuration and monitoring. Continuous delivery and DevOps workflows
What are the strengths of Ansible?
No agents required, minimal footprint. Readable, human-friendly YAML syntax. Large ecosystem of modules and roles. Strong community support. Flexible for cloud, on-prem, and hybrid environments
What are the limitations of Ansible?
Performance can lag on large-scale infrastructures. Complex orchestration may require careful playbook design. YAML syntax errors can cause execution failures. Limited GUI for advanced workflow management (requires AWX/Tower). Debugging idempotency issues may be tricky
How can I practice Ansible typing speed?
