# Get started with IaCM

Welcome to the Harness IaCM onboarding guide. Discover how Harness streamlines and secures your infrastructure management with Infrastructure as Code Management (IaCM).

### What is IaCM? <a href="#what-is-iacm-iacm-what-is-iacm" id="what-is-iacm-iacm-what-is-iacm"></a>

IaC automates infrastructure management via code. IaCM enhances this by ensuring consistent, accountable, and repeatable deployments. Harness boosts IaCM with [**real-time cost estimation**](/infrastructure-as-code-management/platform/workspaces/cost-estimation.md), [**automated policy enforcement**](/infrastructure-as-code-management/platform/policy-and-governance/terraform-plan-cost-policy.md), and [**drift detection**](/infrastructure-as-code-management/platform/iacm-pipelines/operations-overview.md), ensuring efficient provisioning and compliance with standards.

**TERRAFORM TO OPENTOFU MIGRATION**

Harness IaCM supports integration with all **OpenTofu** versions.\
For **Terraform**, we support all MPL versions up to **1.5.x**, any BSL versions (from 1.6.0) are not supported.

Follow this [**OpenTofu migration guide**](https://opentofu.org/docs/intro/migration/) to transition from Terraform to OpenTofu and leverage the benefits of this open-source alternative.

### Next steps <a href="#next-steps-iacm-next-steps" id="next-steps-iacm-next-steps"></a>

This guide introduced you to the core functionalities and setup of Harness IaCM, from creating workspaces to configuring pipelines. To enhance your experience and team efficiency, get the most out of Harness IaCM's built-in reusable features, including:

* [Workspace templates](/infrastructure-as-code-management/platform/workspaces/workspace-templates.md): Quickly create workspaces with predefined, customizable templates.
* [Module Registry](/infrastructure-as-code-management/registry/module-registry.md): Share and reuse infrastructure modules across teams to standardize deployments.
* [Default pipelines](/infrastructure-as-code-management/platform/iacm-pipelines/default-pipelines.md): Start with ready-made pipeline templates to accelerate automation and apply best practices.
* [Queue step](/infrastructure-as-code-management/platform/iacm-pipelines/operations-overview.md): Serialize pipeline executions to track concurrent executions and prevent state conflicts.
* [Harness CLI](/infrastructure-as-code-management/use-iacm/iacm-cli-commands/harness-cli.md): Install the unified CLI to list, get, and execute IaCM workspaces from your terminal.
