We will look at three ways of creating an EC2 instance: manually via the Management Console, with the AWS Command Line Interface (CLI), and with Terraform.

Creating an instance through the Management Console

Just to get a feel of the AWS Management Console and to fully understand how much Terraform simplifies working with AWS, let's create a single EC2 instance manually:

  1. Log in to the console and choose EC2 from the list of services:
  1. Click on Launch Instance:
  1. Choose AWS Marketplace from the left sidebar, type Centos in the search box, and click on the Select button for the first search result:
