Amazon Managed Streaming for Apache Kafka (Amazon MSK) Serverless now supports writes and reads from Kafka clients written in all programming languages. Administrators can simplify and standardize access control to Kafka resources using AWS Identity and Access Management (IAM). Amazon MSK’s IAM support is based on SASL/OAUTHBEARER, an open standard for authorization and authentication. Amazon MSK Serverless is a cluster type for Amazon MSK that allows you to run Apache Kafka without having to manage and scale cluster capacity. MSK Serverless automatically provisions and scales compute and storage resources, so you can use Apache Kafka on demand.
