Why Use Terraform Remotely?
We've now seen how to build, change, and destroy infrastructure from a local machine. This is great for testing and development, however in production environments it is more responsible to run Terraform remotely and store a master Terraform state remotely.
Atlas is HashiCorp's solution for Terraform remote runs and infrastructure version control. Running Terraform in Atlas allows teams to easily version, audit, and collaborate on infrastructure changes. Each proposed change generates a Terraform plan which can be reviewed and collaborated on as a team. When a proposed change is accepted, the Terraform logs are stored in Atlas, resulting in a linear history of infrastructure states to help with auditing and policy enforcement. Additional benefits to running Terraform remotely include moving access credentials off of developer machines and releasing local machines from long-running Terraform processes.
How to Use Terraform Remotely
You can learn how to use Terraform remotely with our interactive tutorial or you can follow the outlined steps below.
First, configure Terraform remote state storage with the command:
$ terraform remote config -backend-config="name=ATLAS_USERNAME/getting-started"
Replace ATLAS_USERNAME with your Atlas username. If you don't have one, you can
create an account here.
Next, push your Terraform configuration to Atlas with:
$ terraform push -name="ATLAS_USERNAME/getting-started"
This will automatically trigger a terraform plan, which you can
review in the Environments tab in Atlas.
If the plan looks correct, hit "Confirm & Apply" to execute the
infrastructure changes.
Version Control for Infrastructure
Running Terraform in Atlas creates a complete history of infrastructure changes, a sort of version control for infrastructure. Similar to application version control systems such as Git or Subversion, this makes changes to infrastructure an auditable, repeatable, and collaborative process. With so much relying on the stability of your infrastructure, version control is a responsible choice for minimizing downtime.

You now know how to create, modify, destroy, version, and collaborate on infrastructure. With these building blocks, you can effectively experiment with any part of Terraform.
Next, we move on to features that make Terraform configurations slightly more useful: variables, resource dependencies, provisioning, and more.
