# MSK Broker Node

An MSK Broker Node in Amazon Managed Streaming for Apache Kafka (MSK) represents an individual Kafka broker within a cluster. Each broker node handles read and write requests, stores message data, and participates in replication for fault tolerance. The node's configuration, such as instance type and storage, determines performance and capacity.
