What is Ansible?
Ansible is an open-source automation tool that helps IT professionals manage and deploy software applications, services, and other IT resources. It is designed to simplify the process of managing complex IT environments by automating tasks, such as configuration management, application deployment, and continuous delivery. Ansible uses a simple, agentless architecture that relies on SSH or WinRM connections to manage nodes, making it easy to deploy and manage.
