Terraform for ML Infrastructure

Infrastructure as code makes cloud resources declarative and reviewable. Terraform configuration describes providers, resources, modules, variables and outputs. The provider communicates with a cloud or service API. Terraform state records the relationship between declared resources and real infrastructure so the tool can calculate changes. The common workflow is initialize providers, review a plan and apply approved changes. ML infrastructure may include GPU instances or node pools, object storage for datasets and artifacts, network endpoints, identities, logging and autoscaling. Resource choices depend on workload shape, region capacity, accelerator availability and cost. GPU quota or stock can vary, and a syntactically valid plan does not guarantee the provider can create the resource. Use small modules with explicit inputs and outputs, and separate environments where appropriate. State is sensitive operational data. It may contain identifiers and values that should not be exposed. Store it in a protected remote backend, restrict access and use locking where supported to prevent concurrent writers. Do not commit state files or credentials. Provider versions and module inputs should be controlled so a future initialization does not unexpectedly alter resource behavior. Review plans in CI but keep apply permissions narrow, especially for production. Terraform can provision the infrastructure around an ML model but does not assess model quality. A resource plan may create a serving endpoint that faithfully hosts an unevaluated candidate. Keep model registry identity and validation gates separate, then reference the approved artifact in deployment configuration. Destroying a resource can delete important data or interrupt service, so inspect destructive changes and preserve backups. Infrastructure code supports repeatability and auditability when state, credentials and review are managed carefully; it does not eliminate cloud-provider differences, quota failures or operational responsibility.
