Pulumi Cloud vs Self-Managed Object Storage for Data-Residency and Access-Control Constraints

Pulumi Cloud vs Self-Managed Object Storage for Data-Residency and Access-Control Constraints

Our team must choose a Pulumi state backend that satisfies strict data-residency and access-control requirements while preserving operational visibility. Pulumi Cloud offers managed encryption, organization-level RBAC, and audit logs, but stores state in a third-party SaaS environment that may conflict with sovereignty policies. Self-managed backends such as S3, Azure Blob, or GCS keep state inside our own cloud account and integrate with native IAM, yet require manual configuration of bucket policies, encryption keys, versioning, and access logging.

The unresolved trade-off is that Pulumi does not provide a unified policy layer across both backend types. RBAC granularity and audit retention differ significantly between Pulumi Cloud and self-managed storage, and backend-specific behaviors—including server-side encryption defaults and the exact IAM permissions required to read and write state—change across Pulumi versions. We need to determine whether a vendor-operated backend is acceptable or whether full cloud-account ownership of infrastructure metadata is mandatory.

Does Pulumi Cloud's organization-level RBAC and audit logging meet strict data-residency requirements when state is stored in a third-party SaaS region, or is a self-managed backend required? For self-managed object storage, what is the minimal set of IAM permissions and bucket policy conditions needed to prevent accidental public access while still allowing Pulumi to read and write state? Is there a documented way to unify audit retention and access granularity across Pulumi Cloud and self-managed backends, or must teams accept divergent policy models?
