 ### Remote
 
 In this mode the ruler delegates rules evaluation to the query-frontend. When enabled, the ruler leverages all the query acceleration techniques employed by the query-frontend, such as [query sharding]({{< relref "../../query-sharding/index.md" >}}).
 To enable the remote operational mode, set the `-ruler.query-frontend.address` CLI flag or its respective YAML configuration parameter for the ruler.
 Communication between ruler and query-frontend is established over gRPC, so you can make use of client-side load balancing by prefixing the query-frontend address URL with `dns://`.

 ## Recording rules
 
 The ruler evaluates the expressions in the [recording rules](https://prometheus.io/docs/prometheus/latest/configuration/recording_rules/#recording-rules) at regular intervals and writes the results back to the ingesters.
