Intro

IT automation
Configuration management
Automatic deployment
Push/Pull Architecture
Pull Architecture
Nodes check with the server periodically and fetch the configurations from it
Examples are Chef & Puppet
Requires clients to be installed on the nodes i.e Master/Slave architecture
Push Architecture
Server pushes configuration via ansible modules (small programs) to the nodes
Ansible uses the push architecture
It uses agentless approach since it uses SSH to deploy the configuration on the nodes
We can also use custom authentication protocols like Kerberos via plugins
Ansible Architecture
Have a Local Machine where Ansible is installed
Nodes are the systems to be configured. They are controlled by the local machine
Module is collection of configuration files
These config files are called playbooks
Inventory is a document that groups the nodes under specific labels
