2 | How Exactly Ansible Works: A Step-by-Step Guide for Beginners

00:00 In Ansible, there are two machines - the controller and the host.
01:05 Ansible is agentless and can be installed on the controller machine, not the host systems.
02:05 Ansible works by installing it on a machine and creating files with instructions for the host systems
02:58 Ansible uses playbooks to control multiple machines or perform various configurations from a single controller.
03:57 Inventory file stores information about host systems and allows grouping of hosts.
04:55 An inventory file is used to define groups and host machines in Ansible.
05:51 Ansible Playbooks are used to define tasks and instructions for hosts
06:57 Ansible works by using Playbook and inventory files to perform tasks on a host machine.

How Ansible Works?
*Controller*
In Ansible, the "controller" is the machine where you run Ansible commands or playbooks
Ansible controller is the machine or server that manages the configuration and deployment of software to other machines (hosts)
The controller can be any machine that meets the requirements for running Ansible, such as a laptop, a desktop computer, a virtual machine, or a cloud-based instance

*Host*
Ansible host is any machine that Ansible is managing
This can be a physical server, a virtual machine, or a cloud-based instance

Inventory File lists the IP addresses or domain names of those servers (hosts), and categorizes them under a group e.g. "groupA"

You might also specify some properties for each server, such as the username and password needed to connect to it over SSH

Once you have defined your inventory, you can write Ansible playbooks that target specific groups or individual hosts

For example, you might write a playbook that installs a web server software package on all the hosts in the "groupA" group

Awesome Explanation sir, I enjoyed your session

Good One, however, I have a question - if I have to perform an unattended installation of Windows on a few hosts, I will go for an Unattended Installation, then what is the different role that Ansible plays ?

Hi sir, I am doing execution using jmeter tool and observed high cou utilization due to java code which i have written 😢 and now client is asking me to find the solution for this one.
Digest and signature creation is available in coding by calling the class from the jar file. Can we have may solution to optimise this one
