What is Ansible

Ansible is an open-source tool for provisioning, deployment of application and configuration management. It runs on several Unix-like systems, and might piecet each Unix-like systems similarly as Microsoft Windows. It includes its own declarative language to explain system configuration.
Ansible is a Red Hat provided tool for automating platform and IT configuration management. It uses human-readable YAML/YML templates so users will program repetitive tasks to occur mechanically, while not learning a sophisticated language.

Ansible uses the hosts file wherever one will cluster the hosts and might management the actions on a selected cluster within the playbooks.

What is Configuration Management

A product performance and consistency can be smoothly established and maintained using Configuration management with their functional and physical attributes with its design and operational data throughout its life.

Types of Configuration Management Tool

There are various types of configuration management tool available, few of them are as follows:-

1. Ansible
   
   Ansible is based on SSH, so it doesn’t require to install any agents on remote nodes.Its playbook structure is easy and crystal clear structured to understand.It has a more streamlined codebase compared to some other tools. It is idempotent and it has high interoperability.
2. Chef
   
   Chef follows the Push based model and allows cloud adoption.It helps to increase service resiliency, to develop more defect-free software as it captures bugs before they occur and also helps to improve risk management. Chef’s automation talents are able to lower risk and improve compliance in any respect stages of the development life cycle.
3. Puppet
   
   Puppet has robust compliance in automating and news tools. It provides active community support across development tools and it also provides Intuitional web UI to handle multiple tasks, which includes reporting and real-time node management.
4. Saltstack
   
   It is simple, Straight and usage is easy once you go through the setup phase.Saltstack has a DSL(Domain Specific Language) feature so it doesn’t require logic and states.Saltstack’s Input, output, and configs are very stable and consistent because it uses the concept of YAML/YML.The introspection feature plays a handy role as it makes simple to look at what is happening inside Salt.

How Ansible Works?

Ansible connects to your nodes and push tiny programs, known as “Ansible modules” to make its smooth working. Your library of modules will reside on any machine, and there are not any servers, daemons, or databases needed.
