Article 17 – OCI IAM Cross-Tenancy Access & Compartment Delegation Architectures

1. Introduction to Multi-Tenancy Governance In enterprise cloud operations, organizations often maintain multiple distinct OCI Tenancies—such as separate tenancies for different subsidiaries, independent business units, or Managed Service Provider (MSP) partner access. By default, OCI tenancies are completely isolated cryptographic…
