Ansible is one of the widely used tools in DevOps automation for configuration management, especially when compared with Chef and Puppet. There are several reasons for its popularity.
Agentless approach: One of Ansible’s key features is its agentless model, which avoids the overhead of installing and maintaining agents on managed systems. It is easy to get started with, and it typically uses SSH key-based authentication for Linux/Unix systems.
YAML-based playbooks: Ansible playbooks are written in YAML, which is human-friendly and does not require learning a new programming language. This lowers the learning curve for DevOps engineers and fits well with tools such as Kubernetes and Docker.
Disadvantages: There are also some limitations when compared with Chef and Puppet.
Less declarative enforcement: Unlike Puppet, Ansible is often more task-oriented than declarative. This gives users more control over execution flow, but it is less focused on continuous state enforcement.
No continuous drift correction by default: Ansible does not continuously monitor and reconcile system state on its own. If someone changes a server manually, Ansible will not correct that change until you run automation again.
