+For an API Management self-hosted gateway, caching requires an external cache. For caching to be effective, a self-hosted gateway and the cache it relies on must be located close to each other to minimize lookup and store latencies. Deploying a Redis cache into the same Kubernetes cluster or in a separate cluster nearby are the best options.

 ## Use the external cache
 
 After adding a Redis-compatible cache, configure [caching policies](api-management-policies.md#caching) to enable response caching, or caching of values by key, in the external cache.
 
 For a detailed example, see [Add caching to improve performance in Azure API Management](api-management-howto-cache.md).
