What should be considered when using a Fault Domain for instance placement?

When considering the use of a Fault Domain for instance placement, the primary focus is on optimizing available capacity within an availability domain. Fault Domains are an essential feature in Oracle Cloud Infrastructure that helps you enhance the availability and fault tolerance of your applications by isolating groups of compute resources from each other. By strategically placing instances across multiple Fault Domains, you can ensure that if one Fault Domain experiences issues, the others remain unaffected, allowing for continued operation of your workloads.

Using Fault Domains effectively optimizes capacity by distributing workloads across different physical hardware within the same availability domain, thereby reducing the risk of resource contention and promoting higher availability. This distribution allows for better resource management and potential scalability, particularly in scenarios where workloads demand high availability.

Other options present different concepts that do not align with the primary function of Fault Domains. While they all touch on aspects related to instance management and deployment, they do not directly relate to the capacity optimization goal that Fault Domains serve.
