Terraform for beginners | Terraform for Dummies | Terraform Explained with Examples

Terraform is a cross-platform tool, which means that it does not only interact with AWS — it can also interact with a multitude of other platforms, such as GCE, VMware, OpenStack, and Azure.

The main benefit of it is that rerunning a declarative definition will never do the same job twice, whereas executing the same shell script will most likely break something on the second run.Terraform provides special configuration language to declare your infrastructure in simple text templates.

Terraform also implements a complex graph logic, which allows you to resolve dependencies, intelligibility and reliability. When it comes to servers, Terraform has multiple ways of configuring and wiring them up with existing configuration management tools. Terraform keeps track of the current state of the infrastructure it created and applies delta changes when something needs to be updated, added, or deleted. It also provides a way to import existing resources and target only specific resources.
Terraform is easily extendable with plugins, which should be written in the Go programming language.
