MSK Express brokers now support Intelligent Rebalancing at no additional cost, and with no action required

Effective today, all new Amazon MSK Provisioned clusters with Express brokers will support Intelligent Rebalancing at no additional cost. This new capability makes it effortless for customers to execute automatic partition balancing operations when scaling their Kafka clusters up or down. Intelligent Rebalancing maximizes the capacity utilization of MSK Express-based clusters by optimally rebalancing Kafka resources on them for better performance, eliminating the need for customers to manage partitions themselves or via third-party tools. Intelligent Rebalancing performs these operations up to 180 times faster compared to Standard brokers.

MSK Express brokers are designed to deliver up to three times more throughput per-broker, scale up to 20 times faster, and reduce recovery time by 90 percent as compared to Standard brokers running Apache Kafka. With Intelligent Rebalancing, MSK Express-based clusters are continuously monitored for resource imbalance or overload based on intelligent Amazon MSK defaults to maximize cluster performance. When required, brokers are efficiently scaled, without affecting cluster availability for clients to produce and consume data. Customers can now take full advantage of the scaling and performance benefits of MSK Provisioned clusters for Express brokers while simplifying cluster management operations.

Intelligent Rebalancing is being rolled out for all new MSK Provisioned clusters with Express brokers in all AWS Regions, where Express brokers are available. Intelligent Rebalancing does not require any additional configuration or setup to get started. To learn more, see the Amazon MSK Developer Guide.
