Editing the Fault Domain for an Instance
You can change the fault domain where a virtual machine (VM) instance is placed.
A fault domain is a grouping of hardware and infrastructure that is distinct from other fault domains in the same availability domain. By properly leveraging fault domains you can increase the availability of applications running on Oracle Cloud Infrastructure. For more information and best practices, see Fault Domains.
For permissions, see Required IAM Policy for Working with Instances.
