​
Cluster Overview

A StreamNative instance comprises one or more StreamNative clusters that operate in unison. Clusters can be distributed across geographical locations and can replicate among themselves using geo-replication.
In StreamNative Console, you can create one and only one cluster for an instance.

​
Cluster Features and Usage limits

You can find the features and usage limits of different Clusters in Cluster Types and Regions. For details about how to work with clusters, such as creating, editing, checking, and deleting clusters, see work with clusters.

​
Cluster Location

Each StreamNative cluster is associated with a geographical location. The locations are available at Cluster Types & Regions in StreamNative Cloud.

​
Cluster Protocols and Settings

Each StreamNative Cluster has a set of protocols and settings that you can enable, disable, and configure. For details, see:

​
Cluster Service URLs

Once provisioned, a StreamNative cluster is accessible through service URLs. A service URL is an HTTPS or TLS endpoint that is exposed to the Internet or private network and protected by authentication methods (OAuth2 and API Keys). The Fully Qualified Domain Name (FQDN) of a service endpoint is based on the name of the StreamNative cluster. StreamNative Cloud provides the following service URLs for a StreamNative cluster:
  • Pulsar HTTP Service URL: the HTTP URL of a StreamNative cluster. After being granted the Admin access right, you can use the pulsar-admin or pulsarctl CLI tool to connect to and manage the StreamNative cluster.
  • Pulsar Broker Service URL: the broker URL of a StreamNative cluster. After being granted the produce and consume permissions, you can use the pulsar-client CLI tool or Pulsar clients to connect to and communicate with the StreamNative cluster.
  • Pulsar WebSocket Service URL: the URL for a WebSocket-enabled StreamNative cluster. After being granted the Admin access right, you can use the WebSocket API to connect to and communicate with the StreamNative cluster.
  • Kafka Service URL: the URL for a StreamNative cluster with the Kafka protocol enabled. After being granted the Admin access right, you can use the Kafka CLI tool or Kafka clients to connect to and communicate with the StreamNative cluster.
  • Kafka Schema Registry Service URL: the URL for Kafka Schema Registry service enabled on a StreamNative cluster.
  • MQTT Service URL: the URL for MQTT service enabled on a StreamNative cluster.
