AWS Simple VPC + EC2 Instance

Terraform is an open source "Infrastructure as Code" tool, used by DevOps and SysOps engineers to codify their cloud infrastructure requirements.

In this lesson you'll learn about Terraform from the ground up, and how it can be used to codify infrastructure. Terraform can be used to provision infrastructure across multiple cloud providers including AWS which this lesson will focus on.
