Which service is used for real-time analytics on streaming data?

Amazon Kinesis Data Analytics is specifically designed for real-time analytics on streaming data. It enables users to process and analyze real-time data from sources like Amazon Kinesis Data Streams and can also integrate with other AWS services. This service allows you to run SQL queries on streaming data, which means you can monitor, process, and gain insights from data as it is generated, making it essential for applications that require immediate analytics, such as live monitoring or real-time dashboards.

Other services mentioned serve different purposes: Amazon EMR is primarily used for big data processing and batch analytics using frameworks like Apache Hadoop and Apache Spark, which are not focused on real-time data analysis. AWS Glue is primarily an ETL (Extract, Transform, Load) service designed for preparing and transforming data for analysis, rather than for real-time analysis. Amazon RDS is a managed relational database service that handles structured data and is optimized for transactional workloads, not specifically for real-time streaming data analytics.
