It seems like AWS is renaming some of their services to refer to the underlying open-source software by name. This makes sense when AWS is just running the underlying software for the customer without too much changes, like Amazon Managed Grafana, Amazon Managed Streaming for Apache Kafka.
Today we are announcing the rename of Amazon Kinesis Data Analytics to Amazon Managed Service for Apache Flink, a fully managed and serverless service for you to build and run real-time streaming applications using Apache Flink.
