Amazon Kinesis Data Streams
Amazon Kinesis Data Streams (KDS) is a massively scalable and durable real-time data streaming service. KDS can continuously capture gigabytes of data per second from hundreds of thousands of sources such as website clickstreams, database event streams, financial transactions, social media feeds, IT logs, and location-tracking events. The data collected is available in milliseconds to enable real-time analytics use cases such as real-time dashboards, real-time anomaly detection, dynamic pricing, and more.
Benefits
Real-time performance
Make your streaming data available to multiple real-time analytics applications, to Amazon S3, or to AWS Lambda within 70 milliseconds of the data being collected.
Durable
Reduce the probability of data loss. Synchronous replication of your streaming data across three Availability Zones in an AWS Region and store that data for up to 365 days to provide multiple layers of protection from data loss.
Secure
Meet your regulatory and compliance needs by encrypting sensitive data within KDS, and privately accessing your data via your Amazon Virtual Private Cloud (VPC). Data can be secured at-rest by using server-side encryption and AWS KMS master keys.
Easy to use
Build your streaming applications quickly using the AWS SDK, the Kinesis Client Library (KCL), connectors, and agents. Easily process data with built-in integrations to AWS Lambda, Amazon Kinesis Data Analytics, Amazon Kinesis Data Firehose, and AWS Glue Schema Registry.
Elastic
Dynamically scale your applications. Kinesis data streams scale from megabytes to terabytes per hour, and scale from thousands to millions of PUT records per second. You can dynamically adjust the throughput of your stream at any time based on the volume of your input data.
Low cost
Kinesis Data Streams has no upfront cost, and you only pay for the resources you use. For as little as $0.015 per hour, you can have a Kinesis data stream with 1MB/second ingest and 2MB/second egress capacity.
How it works

Use cases
Log and event data collection
Kinesis Data Streams can be used to collect log and event data from sources such as servers, desktops, and mobile devices. You can then build Kinesis Applications to continuously process the data, generate metrics, power live dashboards, and emit aggregated data into stores such as Amazon S3.
Real-time analytics
You can have your Kinesis Applications run real-time analytics on high frequency event data such as sensor data collected by Kinesis Data Streams, which enables you to gain insights from your data at a frequency of minutes instead of hours or days.
Mobile data capture
Gaming data feed
Kinesis Data Streams can be used to continuously collect data about player-game interactions and feed the data into your gaming platform. With Kinesis Data Streams, you can design a game that provides engaging and dynamic experiences based on players’ actions and behaviors.
