Terraform Cloud is HashiCorp's managed service for infrastructure automation that is engineered to help teams manage infrastructure with Terraform in a collaborative and efficient manner. Terraform Cloud provides a cloud-based platform where users can securely run, manage, and collaborate on Terraform workflows. Unlike the open-source version of Terraform, Terraform Cloud simplifies the management of infrastructure by offering a hosted environment for IaC, leaving engineers free from local execution environments or infrastructure automation tooling.
The importance of Infrastructure as Code is that it makes possible automation, ensuring the infrastructure gets deployed faster and in a more reliable manner. Codifying infrastructure means that a team can manage, version, and replicate environments consistently across development, testing, and production. With IaC, human error becomes minimal since standardized configurations make repeatability a success. It's better to collaborate, since code can be reviewed, tested, and stored in version control. That way, IaC is likely to add the scalability aspect since it provides for the dynamic provisioning of infrastructure according to demand, thus utilising the resources more properly.

Most organizations now use Infrastructure as Code, but operating Terraform securely at scale is hard – state management, access control, drift, and policy enforcement all become real challenges.
One of the most popular IaC tools is Terraform and one of the platforms that helps manage your Terraform code is Terraform Cloud, now integrated into HashiCorp Cloud Platform as HCP Terraform.
How Terraform Works Locally Versus in the Cloud
What Is Terraform Cloud?
Terraform Cloud removes many of the complexities in trying to maintain your own Terraform state files in a multi-team, collaborative Terraform environment.
The way Terraform works today is that you download Terraform, you get Terraform on your computer and then, when you run Terraform, it talks directly to the cloud providers. You might have AWS here. It might be Azure. Or it might be any number of the hundreds of providers that Terraform supports.
This works great because you can run it on your own machine, you have full control over your data and there's a lot of security associated with it. The downside is that some internal details make this a little bit messy. You have to manage something called a state file.
The state file is the way that Terraform reconciles what you've created and what you want. Otherwise, Terraform wouldn't know whether to create something or update something that already exists. State is always here.
In a SaaS environment this is hidden from the user. If you're using an infrastructure management tool that's hosted, this could be stored in the database, and you never see it.
Terraform Cloud provides a platform for remote state management, collaboration, and CI/CD pipelines for Terraform deployments.
Core Features of Terraform Cloud
Key Features of Terraform Cloud
- Remote State Management: Terraform Cloud enables teams to store their state files remotely making them secure and centralised
Terraform Cloud Features
- Workspaces
Workspaces are the building blocks of Terraform Cloud
The design reduces manual overhead over infrastructure updates and management.
- Policy as Code with Sentinel: Terraform Cloud comes with Sentinel, the policy-as-code framework. This ensures that infrastructure adheres to security, compliance, and operational guidelines. Policies can be written and enforced to stop unauthorized changes.
- Cost Estimation: Among its unique features is the cost estimation feature directly within the product in Terraform Cloud. Before applying a plan by Terraform, users can get an estimate of the cost of the infrastructure resources they are provisioning to effectively manage their budgets on the cloud.
- Private Module Registry: In Terraform Cloud, teams have the capability to create and use private modules that standardize and simplify infrastructure deployments. These modules reduce duplication of code and improve maintainability.
- Notification and Monitoring: The teams receive notifications on infrastructure runs, failures, as well as status updates via Slack and email integrations. It keeps everyone informed in real time.
Workspace-Based Workflow Model
Terraform Cloud offers workspaces to maintain different environments for a project. This is how using Terraform Cloud works:
- Create Workspaces: A workspace can be formed as an environment or a project. Workspaces apply Terraform configurations and store state within.
- Connect the VCS Repositories: Have plans automatically triggered and applied with a link to your VCS repository.
- Plan and Apply: Terraform Cloud automatically runs terraform plan to present the proposed changes and automatically receives approval before applying (terraform apply).
- Monitor and Manage State: State files are automatically saved and managed and monitored via the workspace, and infrastructures are updated automatically.
The typical CLI interaction that Terraform Cloud orchestrates is:
bash
terraform plan
terraform apply
Terraform Cloud assumes these commands run remotely in a managed environment rather than on a local machine, with the state handled centrally.
Terraform Cloud Versus Terraform Enterprise
Terraform Cloud vs Terraform Enterprise
The main difference between Terraform Cloud and Terraform Enterprise is that Terraform Cloud is a SaaS product by Hashicorp, while Terraform Enterprise is a self-hosted and self-managed solution.

|---|---|---|
| Deployment model | SaaS | Self-hosted and self-managed solution |
| Management | Managed service platform | Self-managed |
| Remote execution | Built-in remote execution | Self-managed |
| Typical use | Collaborative team workflows in cloud | On-premises control |
The choice between the two depends on organizational requirements for control, compliance, and hosting preferences.
