2.4 Initial Cloud Account (Tenancy) Architecture

  • Once the Cloud Account environment is created, users will be managed by OCI Native IAM. Oracle Identity Cloud Service (IDCS) was initially Federtion as an Identity Provider as a relic of OCI Classic.
  • Administrator of OCI has all privileges of the OCI Tenancy
  • The OCI_Administrator group in IDCS is mapped to an Administrator group in OCI. When you log into OCI Console as SSO, you are actually a user in OCI_Administrator, but on OCI they are treated as Administrator groups and have related permissions.
  • When you create a user on IDCS, ex) when the neo@example.com user is created, it is automatically synchronized and an oracleidentitycloudservice/neo@example.com is created on OCI.
  • Compartment, a compartment for OCI resources, has the original Root Compartment and needs to be added if needed Figure
