Streams Messaging: Light Duty cluster layout

You can use a Streams Messaging: Light Duty cluster definition in development, testing, or proof of concept scenarios. Each of the cluster nodes includes:

  • Kafka Broker, ZooKeeper, and the SRM driver are co-located on all instances

  • For each node hosting Kafka Broker, ZooKeeper, and the SRM driver instances:
    • AWS: m5.2xlarge
    • Azure: D8_v3
  • Storage configuration per Kafka Broker node:
    • AWS: 1 TB Volume EBS ST1
    • Azure: 4x 500GB Standard SSD
  • Master node instance
    • AWS: m5.2xlarge
    • Azure: Standard_D16_v3
  • Storage configuration for Master node:
    • AWS: 100 GB Volume EBS Magnetic
    • Azure: 100 GB Standard Locally-redundant SSD storage
