# REL 10. How do you use fault isolation to protect your workload?
<a name="rel-10"></a>

Fault isolation limits the impact of a component or system failure to a defined boundary. With proper isolation, components outside of the boundary are unaffected by the failure. Running your workload across multiple fault isolation boundaries can make it more resilient to failure.
