Azure private networking options

Imply Polaris ingests data from publicly available sources by default. For cases where network traffic cannot traverse over the public internet, either due to configuration or security requirements, Polaris offers several private connectivity options. This topic covers private networking between Microsoft Azure and Polaris. For information about AWS, see AWS private networking options.

Ingest data from Azure Blob Storage​

You can establish a secure connection from Azure Blob Storage to Polaris using Azure Private Link. This ensures that all network traffic between Polaris and your storage account traverses over a private endpoint and remains within the Microsoft backbone network, avoiding the public internet. For more information, see Azure Private Link for ingesting data from Azure Blob Storage.

Publish data from an event stream​

You can use Azure Private Link to establish a unidirectional secure connection from your Azure virtual network (VNet) to Polaris over a private endpoint for querying and publishing data from an event stream. When you query Polaris endpoints through Azure Private Link, traffic between your Azure VNet and Polaris remains within the Microsoft backbone network and doesn't traverse the public internet. For more information, see Azure Private Link for querying and publishing data.

Consume data from an event stream​

For consuming event data from an Apache Kafka cluster hosted on Azure, Polaris supports the following options:

  • Private Link service for Azure Event Hubs: This solution allows Polaris to consume event data from an Azure Event Hubs namespace. For more information, see Connect to Azure Event Hubs.
  • Private Link service for multi-availability zone clusters: This solution allows Polaris to consume event data from multi-availability zone Kafka clusters. For more information, see Connect to a multi-availability zone cluster.
  • Private Link service for single availability zone clusters: This solution allows Polaris to consume event data from single availability zone Kafka clusters. For more information, see Connect to a single availability zone Kafka cluster.
