In this article, we will discuss “Difference between Kinesis Data Stream and Kinesis Firehose”. Today, I will explain the difference between Kinesis Data Stream and Kinesis Firehose. AWS constantly offering the new features and functionality. Kinesis is known as highly available communication channel to stream messages between data producers and data consumers.

Data Producers: Source of data such as system or web log data, social network data, financial data, mobile app data, telemetry from connected IoT devices, or etc.
Data Consumers: Data processing and storage applications such as Amazon Simple Storage Service (S3), Apache Hadoop, Apache Storm, ElasticSearch, or etc.

It is important to understand Kinesis first. Amazon Kinesis is a significant feature in AWS for easy collection, processing, and analysis of video and data streams in real-time environments. AWS Kinesis helps in real-time data ingestion with support for data such as video, audio, IoT telemetry data, application logs, analytics applications, website click-streams, and machine learning applications.

Amazon Kinesis Data Streams is used to collect and process large streams of data records in real time. There are no servers to manage. A typical Kinesis Data Streams application reads data from a data stream as data records. The on-demand mode eliminates the need to provision or manage capacity required for running applications. Adjust your capacity to stream gigabytes per second of data with Kinesis Data Streams. Get automatic provisioning and scaling with the on-demand mode. Pay only for what you use with Kinesis Data Streams. With the on-demand mode, you don’t need to worry about over-provisioning. Use built-in integrations with other AWS services to create analytics, server-less, and application integration solutions on AWS quickly.

Amazon Kinesis Firehose

Amazon Kinesis Data Firehose is the easiest way to load streaming data into data stores and analytics tools. It is a fully managed service that makes it easy to capture, transform, and load massive volumes of streaming data from different sources into Amazon S3, Amazon Redshift, Amazon Open Search Service, Kinesis Data Analytics, generic HTTP endpoints, and etc.
