-You can customize resilience behavior throughout Foundatio by implementing [`IResiliencePolicyProvider`](https://github.com/FoundatioFx/Foundatio/blob/master/src/Foundatio/Utility/ResiliencePolicy.cs) and registering it with dependency injection. This allows you to replace the default retry behavior in caching, queues, storage, and other Foundatio components.
