 Monolithic mode is useful for getting started quickly to experiment with Loki, as well as for small read/write volumes of up to approximately 20GB per day.
 
-You can horizontally scale a monolithic mode deployment to more instances by using a shared object store, and by configuring the [`ring` section](https://grafana.com/docs/loki/<LOKI_VERSION>/configure/#common) of the `loki.yaml` file to share state between all instances, but the recommendation is to use simple scalable mode if you need to scale your deployment.
