A fault domain is a grouping of hardware and infrastructure within an availability domain. Each availability domain contains three fault domains. Fault domains provide anti-affinity: they let you distribute your instances so that the instances are not on the same physical hardware within a single availability domain. A hardware failure or Compute hardware maintenance event that affects one fault domain does not affect instances in other fault domains. In addition, the physical hardware in a fault domain has independent and redundant power supplies, which prevents a failure in the power supply hardware within one fault domain from affecting other fault domains.

Usually fault domains to do the following things:

1) Protect against unexpected hardware failures or power supply failures.

2) Protect against planned outages because of Compute hardware maintenance.

The primary goal for distributing resources across multiple availability domains in Oracle Cloud Infrastructure is to improve fault tolerance and high availability. An availability domain is one or more data centers located within a region that have fault-tolerant power and network connectivity. Availability domains are isolated from each other within a region, which provides protection from failures that affect multiple data centers at once. By distributing resources across multiple availability domains, users can ensure that their applications can continue to run even if one availability domain becomes unavailable.
