Terraform

Terraform is a free downloadable tool that you can interact with on the command line. It allows you to provide infrastructure on any cloud provider and handle configuration, plugins, and state. This open-source tool lets you specify on-prem and cloud resources in human-readable configuration files, which you can reuse, version, and share. Moreover, Terraform can handle low-level components (including storage, compute, and networking resources) and high-level components (including DNS entries and SaaS features).

• It allows you to build a "self-serve" infrastructure model that allows product teams to manage their own infrastructure independently.
• Using Terraform, you can codify the setup required for a Heroku application, configure a DNSimple, and set up Cloudflare as a CDN (Content Delivery Network) for the app.
• Terraform lets you rapidly spin up and decommission infrastructure for development, test, QA, and production.
• Using it, you can create, provision, and bootstrap a demo on diverse cloud providers.
