Amazon Kinesis – Managed service for real-time data processing

Amazon Kinesis Firehose is a managed service to load real-time streaming data to Amazon Simple Storage Service (S3), Redshift or Elastic search Service (ES). Firehose is part of the Amazon Kinesis streaming data platform, along with Amazon Kinesis Streams and Amazon Kinesis Analytics. There is no need to write applications or manage resources with Firehose. Applications can easily be configured to send data to Firehose and it automatically loads the data on the destination specified.

It enables near real-time analytics with existing business intelligence tools and dashboards. It automatically scales to match the throughput of your data and requires no ongoing administration. It can even compress and encrypt the data before loading, thus, minimizing the amount of storage used at the destination and increasing security.

Firehose delivery stream can easily be created and configured from the AWS Management Console, and data sending to the stream can be started in just a few minutes.
