With the below Infrastructure as Code video 🎬 you'll get a good overview of what Infrastructure as Code is and how the IaC tools differ from each other.

What is Infrastructure as Code? 🤔

To understand the Infrastructure as Code concept better, I explain how DevOps tasks were done

before automation and
after automation.

► DevOps tasks BEFORE automation

Before automation you were doing everything by hand 🙌🏼:

setup servers
configure networking
install and configure software
etc.

In addition to that all the tasks needed to be done for multiple environments like DEV, TEST and PROD environment. 🤦🏼‍♂️

► DevOps tasks AFTER automation

Now, Infrastructure as Code is a way to automate all these DevOps tasks end to end instead of doing it manually. 🚀
All the knowledge and expertise of system administrators or DevOps engineers are packed into programs and applications that carry out those tasks.

So, Infrastructure as Code or IaC is a concept and there are Infrastructure as Code tools, like Ansible, Puppet, Terraform or Cloudformation etc that you can use for different tasks.

Difference of Infrastructure as Code tools 🛠

Why do we have so many different tools, can't we just use one IaC tool? 🙄

Well, no. Because no tool can do everything and each one is great in a specific area. IaC tools automate tasks in different categories for different phases:

3 main task categories:

infrastructure provisioning
configuration of provisioned infrastructure
deployment of application

Distinction of phases:

initial setup phase
maintaining phase

So, in most cases you would use a combination of 2 or more IaC tools.

Distinction in how they work

Moreover, the IaC tools differ in the way HOW they work:

declarative vs procedural
mutable vs immutable
agent vs agentless
