What is Anisble?

Ansible is an open-source automation tool used for configuration management, application deployment, task automation, and IT orchestration. It uses a simple, human-readable language (YAML) to define automation tasks in 'playbooks'. Ansible works by connecting to nodes (servers, network devices, etc.) over SSH and pushing small programs called Ansible modules to them. These modules are executed on the nodes, and then removed. Because it's agentless, it's easy to deploy and manage, making it a popular choice for automating repetitive tasks and managing complex IT infrastructures.
