Amazon MSK can now automatically expand cluster storage

[Amazon Managed Streaming for Apache Kafka](/msk/) (Amazon MSK) can now automatically expand storage of a MSK cluster, making it easier for you to continuously right-size the storage provisioned. Using Application Auto Scaling policies you set and control both the target cluster storage utilization threshold and a maximum storage limit. These policies will automatically trigger cluster-wide storage expansion by a required amount when the storage utilization threshold is exceeded. Automatic storage expansion is offered at no additional cost and can be used in all [AWS regions where MSK is available](/about-aws/global-infrastructure/regional-product-services/) excluding AWS Europe (Milan). Amazon MSK is a fully managed service for Apache Kafka that makes it easy for you to build and run applications that use Apache Kafka as a data store. Amazon MSK is 100% compatible with Apache Kafka, which enables you to quickly migrate your existing Apache Kafka workloads to Amazon MSK with confidence or build new ones from scratch. With Amazon MSK, you spend more time innovating on applications and less time managing clusters.
