Multi-Cluster Management

Multi-cluster does not mean multi-region, install Kpow in proximity to your Kafka resources.

One instance of Kpow can manage multiple Apache Kafka clusters (and their associated resources). The screenshot below shows Kpow connected to two clusters with the following environment names (and associated connection configuration):

  • ENVIRONMENT_NAME = Plain, and
  • ENVIRONMENT_NAME_2 = ACLCluster

Kpow Switch Clusters UI

When configuring multiple clusters, the first configured cluster is your primary cluster.

The primary cluster holds the Kpow internal topics. You can switch the primary cluster at any time.

Resources

Kpow will manage as many clusters as your license permits - you may have to increase the memory and CPU to ensure that the regular snapshotting process executes within thirty seconds.

Information on snapshotting performance of each cluster is available at 'settings -> performance'.

Configuration

To configure multiple clusters, simply repeat the connection configuration with _2, _3, _4 suffixes.

ENVIRONMENT_NAME for each resource-set is displayed in the Kpow UI when switching cluster.
