Understand the default cluster configuration

The Bitnami Multi-Tier Solution for Kafka uses multiple VMs, consisting of a cluster of one or more brokers to provide a horizontally scalable Kafka cluster where the data/topic is replicated across the selected nodes. The cluster is configured as follows:

• ZooKeeper instances: They are configured in the cluster and running on nodes independently from Kafka.
• Disk: Each Kafka node have a 30GB SSD disk attached (default, configurable).
• Authentication: Client, inter-broker, and Zookeeper authentication.
