Course Overview
This course starts with the basics by providing an overview of Infrastructure-as-Code
(IaC), which is the basic concept for Terraform. We will explore how Terraform can be
used as an IaC tool on Amazon Web Services (AWS) and also cover its features and
benefits. We’ll then look at how Terraform transforms lines of code into real
infrastructure on AWS.
Terraform allows infrastructure to be expressed as code. The desired state is expressed
in a simple human-readable language. Terraform uses this language to provide an
execution plan of changes, which can be reviewed for safety and then applied to make
changes. Extensible providers allow Terraform to manage a broad range of resources,
including hardware, IaaS, PaaS, and SaaS services.
By expressing all infrastructure as code, source code version control techniques (with
Git) become available as a superior change control process, wherein all changes to
systems are tracked, with a full audit history of who made changes, and when the
changes were made.
