Which service does AWS provide for Real Time Big Data analytics?

Kinesis Data Streams is a fully managed service designed specifically for real-time data streaming and analytics. It allows you to collect, process, and analyze real-time data at scale, making it ideal for applications that require immediate insights from large volumes of streaming data. With Kinesis, you can ingest and process data from multiple sources, such as IoT devices, social media feeds, logs, and other real-time data sources.

The service enables you to build custom applications that can consume and respond to real-time data, such as monitoring system performance, tracking user activity, or processing time-sensitive transactions. It supports scalable processing capabilities and can handle real-time analytics workloads efficiently.

In contrast, other options like Elastic Map Reduce (EMR) are more oriented toward batch processing and large-scale analytics rather than real-time processing. S3 Select provides a means to retrieve specific data from objects stored in S3, but it is not designed for real-time big data analytics. Similarly, RDS is a relational database service, well-suited for traditional database tasks but not optimized for real-time big data analytics in the same manner that Kinesis Data Streams is.
