What is ansible and how to install ansible on linux (Fedora/Centos/RHEL)
Ansible Introduction
Ansible is an IT automation tool and can configure any systems, deploy any software on remote machines, and orchestrate advanced tasks such as continuous deployments or zero downtime rolling updates.
Ansible is simple and ease-of-use.
It is an agentless automation tool and manages machines over the SSH protocol.
it does not need a database and will be no daemons to start or keep running on machines.
We need to install ansible on one machine and it can manage an entire group of remote machines from that central point.
Anisble does not need software installed or running on remote machines when manages remote machines.
