Ansible Architecture?
Human –> ACS –> ARS
Human –> tower –> ARS

• Components of Ansible

Ansible , Playbook , inventory , Ansible configuration

• What are the types of Inventory we can pass? inventory with all hosts , group in inventory, group of group in inventories.
• Top 10 Ansible Modules? cmd, file, copy, apt, package, service, python, shell, bash etc.,

It is configuration management tool, which operates by connecting via SSH in linux and WINRM in windows.

• Why We need Ansible? Its Benefits?

Agentless, scalable, extensible and easy to use in cross-platforms

• How Ansible Works?

via control node ACS from where it can be deployed and runs on ARS remote or managed nodes.

• Ansible Architecture?

uses control node to execute tasks on managed nodes.

• Components of Ansible

inventory, modules, plugins, playbooks, roles

• What are the types of Inventory we can pass?

static inventory ini format

• Top 10 Ansible Modules?

ping
shell
command
yum
apt
git
user
service
file
copy

2)Benefits:
Agentless – uses SSH which is already present on most systems
Idempotent – Running a playbook multiple times won’t repeat work
Inventory management – Easily manages all types of server

3)Ansible works by connecting to remote systems over ssh, then executing tasks using modules to manage systems and application

4)*control node– our machine
*Managed node – Traget machine
*inentory , modules, plugins,olaybooks

5)static , dynamic, Inline
,
6)yum, apt, service ,file ,copy ,user, ping ,shell, authorized_key ,group

Why We need Ansible? Its Benefits?
Useful in updating multiple hosts at a time. Benefits are, it is agentless, idempotent and secure.

How Ansible Works?
Ansible works with SSH protocol between Linux to Linux servers while between Linux to Windows, it works with WinRM protocol.

Ansible Architecture?
Ansible’s architecture basically has two major servers. One is Ansible Controller Server (ACS) and the other is Ansible Remote Servers (ARS) 

Components of Ansible
Executables
Inventory
Modules
Plugins
Collections
Global Configuration File (ansible.cfg)

What are the types of Inventory we can pass?
Remote Host IPs
Remote Hostnames
Static
Dynamic

Ansible is a tool which helps to manage for all types of management of the servers, or application using this remotely on Linux or windows environment, with mange of multiple commands which helps to run as remotely and fast.

• Why We need Ansible? Its Benefits?

Ansible is essay to manage various task very fast and simple ways with very much same for all the servers no difference in the task or work whichever is done with the same command.

• How Ansible Works?

Ansible work remote way on Linux it uses SSH and in windows its usages winrm utility with client list because the required utilities are already comes with OS.

• Ansible Architecture?

Ansible is an open-source automation tool that simplifies the works and configuration management, application deployment

• Components of Ansible

• What are the types of Inventory we can pass?

Single, Group and group combination.

Ansbile is a sort of automation tools which offer various python programs and utility to
manage complete infrastructure via command line or via GUI with various options.

Q2. – We need Ansible to perform various automation on list of hosts or inventory, we can also setup & configure hosts at bulk level with less time, it also offer idempotent which is nothing but manage state if any task has been executed at once then it will maintain the state of the activities and only perform required, updated instruction via various commands. It also save time, cost and improve efficiency in work place.

Q3. As a user, we initiate a command via Ansible Controller hosts, with the help of plugins & modules, it perform required instructions on various Ansible hosts/inventories.

Q4. User -> ACS (Ansible, Playbook, Inventories/configuration) -> ARS

Q5. i.) Ansible, ii.) Playbook, iii.) Inventories iv.) configuration

Q6.) file based, command line based in the form of IP/hostname/FQDN

Q7.) copy, apt, file, group, user, git, apt, service, package,

It is a configuration management tool that allows us to manage the configuration in the servers. It is from Redhat and Written in python

Benefits?

It saves time for deployments to 100’s of servers

It saves cost as it is open sources and free.

Configurations are written through coding, that helps for automations.

improves the efficiency in work.

IDEOMPOTENT

How it Works? and architecture?

It has 2 major components.

ACS – Ansible control server

ARS – Ansible Remote server

Below is the flow.

HUMAN —-> ACS —> ARS

Also it has Executables under /usr/bin/ansi*, 

modules which is a python code present in ACS and runs in ARS, 

plugins are the features of ansible, which is also python code running in ACS,

configfile under /etc/ansible/ansible.cfg – contains settings and help to override the default settings.

Components:

Playbook

Inventory

config file

Types of inventory we can pass?

CMD,

file,

script,

directory

Top 10 modules?

  file

directory

user

group

service

apt

yum

cmd

script

bash

package

2] To make work easier by automating task via playbooks. It is agent-less and follows idempotence.

3] Connects to remote machine over SSH and pushes small programs called modules to execute taks. Uses inventory files to define hosts and playbooks

4] Consists of control nodes, modules, playbook and inventory file. Connected via SSH connection

5] Inventory, modules, playbooks, tasks, roles, variables, templates, handlers, plugins, facts

6] 2 types of inventory we can pass: static and dynamic

7] ping, copy, file, yum/apt, service, package, user, group, authorized_key, shell

Why We need Ansible? Its Benefits?
deploy across multiple environments, useful in environments where multiple tasks work independently

How Ansible Works?
it will connects to managed nodes and push the codes with stateless
