What is Terraform?

In this post you will know what is Terraform and their key features. I believe that Terraform is an amazing tool. It was launched in 2014, and is going from “good to best” as compared to other tools.Terraform is the next generation configuration orchestration system. It is loaded with new features and functionalities.

As mentioned, Terraform is a configuration orchestration tool. It works well with any cloud, private on-prem or public. Terraform helps to obtain a safe and convenient design, as well as management and improvement in infrastructure as code. It is a part of Hashicorp Stack and this includes Vagrant, Packer, Consul, Vault, and Nomad, as well. With Terraform, it is possible to provide any application written in any language to any infrastructure. Terraform sounds cool, doesn’t it?

What is Terraform?

Terraform is a tool for building, changing and versioning infrastructure safely and efficiently. It can manage existing and popular service providers as well as a part of a custom in-house solution.

Why we like Terraform?

Infrastructure as Code: 

Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.

Execution Plans: 

Terraform has a "planning" step where it generates anexecution plan. The execution plan shows what Terraform will do when you call apply. This lets you avoid any surprises when Terraform manipulates infrastructure.

Resource Graph: 

Terraform builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, Terraform builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.

Change Automation: 

Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what Terraform will change and in what order, avoiding many possible human errors.
