Amazon MSK Serverless is a cluster type for Amazon MSK that you can use to run Apache Kafka without having to manage and scale cluster capacity. It automatically provisions and scales capacity while managing the partitions in your topics, so you can stream data without thinking about right-sizing or scaling clusters. MSK Serverless is fully compatible with Apache Kafka, so you can use any compatible client applications to produce and consume data.
