Amazon Managed Streaming for Apache Kafka (Amazon MSK) now supports removing brokers from MSK provisioned clusters. Administrators can optimize costs of their Amazon MSK clusters by reducing broker count to meet the changing needs of their streaming workloads, while maintaining cluster performance, availability, and data durability.

Customers use Amazon MSK as the core foundation to build a variety of real-time streaming applications and high-performance event driven architectures. As their business needs and traffic patterns change, they often adjust their cluster capacity to optimize their costs. Amazon MSK Provisioned provides flexibility for customers to change their provisioned clusters by adding brokers or changing the instance size and type.

With broker removal, Amazon MSK Provisioned now offers an additional option to right-size cluster capacity. Customers can remove multiple brokers from their MSK provisioned clusters to meet the varying needs of their streaming workloads without any impact to client connectivity for reads and writes. By using broker removal capability, administrators can adjust cluster’s capacity, eliminating the need to migrate to another cluster to reduce broker count.

Brokers can be removed from Amazon MSK provisioned clusters configured with M5 or M7g instance types. The feature is available in all AWS Regions where MSK Provisioned is supported. To learn more, visit our launch blog and the Amazon MSK Developer Guide.
