+## Deployment Recommendations
+
+Loki is designed to be run in two states:
+* [Monolithic](https://grafana.com/docs/loki/<LOKI_VERSION>/get-started/deployment-modes/#monolithic-mode): Recommended when you are running Loki as part of a small meta monitoring stack.
+* [Microservices](https://grafana.com/docs/loki/<LOKI_VERSION>/get-started/deployment-modes/#microservices-mode): For workloads that require high availability and scalability. Loki is deployed in this mode internally at Grafana Labs.
+
+{{< admonition type="tip" >}}
+Loki can also be deployed in [Simple Scalable mode](https://grafana.com/docs/loki/<LOKI_VERSION>/get-started/deployment-modes/#simple-scalable). For the best possible experience in production, we recommend deploying Loki in *microservices* mode.
