History of Terraform

Terraform was first released in July 2014 by a company named HashiCorp. It is the same company that brought us tool, such as Vagrant, Packer, and Vault. Being the fifth tool in the HashiCorp stack, it focused on providing a way to describe the complete infrastructure as code:

... From physical servers to containers to SaaS products, Terraform is able to create and compose all the components necessary to run any service or application. With Terraform, you describe your complete infrastructure as code, even as it spans multiple service providers. Your servers may come from AWS, your DNS may come from CloudFlare, and your database may come from Heroku. Terraform will build all these resources across all these providers in parallel. Terraform codifies knowledge about your infrastructure unlike any other tool before, and provides the workflow and tooling for safely changing and updating infrastructure. - https://www.hashicorp.com/blog/terraform.html
