 # Azure Monitor managed service for Prometheus remote write
-Azure Monitor managed service for Prometheus is intended to be a replacement for self managed Prometheus so you don't need to manage a Prometheus server in your Kubernetes clusters. You may also choose to use the managed service to centralize data from self-managed Prometheus clusters for long term data retention and to create a centralized view across your clusters. In this case, you can use [remote_write](https://prometheus.io/docs/operating/integrations/#remote-endpoints-and-storage) to send data from your self-managed Prometheus into the Azure managed service.

 ## Architecture
-Azure Monitor provides a reverse proxy container (Azure Monitor [side car container](/azure/architecture/patterns/sidecar)) that provides an abstraction for ingesting Prometheus remote write metrics and helps in authenticating packets. The Azure Monitor side car container currently supports User Assigned Identity and Microsoft Entra ID based authentication to ingest Prometheus remote write metrics to Azure Monitor workspace.

+You can configure Prometheus running on your Kubernetes cluster to remote-write into Azure Monitor Workspace. Currently user-assigned managed identity or Microsoft Entra ID application are the supported authentication types using Prometheus remote-write configuration to ingest metrics to Azure Monitor Workspace.
+
+Azure Monitor also provides a reverse proxy container (Azure Monitor [side car container](/azure/architecture/patterns/sidecar)) that provides an abstraction for ingesting Prometheus remote write metrics and helps in authenticating packets.
+
+We recommend configuring remote-write directly in your self-managed Prometheus config running in your environment. The Azure Monitor side car container can be used in case your preferred authentication is not supported through directly configuration. We plan to add those authentication options to the direct configuration and deprecate the side-car container.
