<tabItem value="self-managed" label="Self-managed">
Self-managed infrastructure allows for managing the cloud resources necessary for a Constellation cluster separate from the Constellation CLI.
This provides flexibility in DevOps and can meet potential regulatory requirements.
To self-manage the infrastructure of your cluster, download the Terraform files for the selected CSP from the [Constellation GitHub repository](https://github.com/edgelesssys/constellation/tree/main/cli/internal/terraform/terraform).
They contain a minimum configuration for the resources necessary to run a Constellation cluster on the corresponding CSP. From this base, you can now add, edit, or substitute resources per your own requirements with the infrastructure
management tooling of your choice. You need to keep the essential functionality of the base configuration in order for your cluster to function correctly.
Make sure all necessary resources are created, e.g., through checking your CSP's portal and retrieve the necessary values, aligned with the outputs (specified in `outputs.tf`) of the base configuration.
Fill these outputs into the corresponding fields of the `constellation-state.yaml` file. For example, fill the IP or DNS name your cluster can be reached at into the `.Infrastructure.ClusterEndpoint` field.
Continue with [initializing your cluster](#the-init-step).
