Amazon Kinesis Video Streams now supports a new cost effective warm storage tier

Posted on: Nov 26, 2025

AWS announces a new warm storage tier for Amazon Kinesis Video Streams (Amazon KVS), delivering cost-effective storage for extended media retention. The standard Amazon KVS storage tier, now designated as the hot tier, remains optimized for real-time data access and short-term storage. The new warm tier enables long-term media retention with sub-second access latency at reduced storage costs.

The warm storage tier enables developers of home security and enterprise video monitoring solutions to cost-effectively stream data from devices, cameras, and mobile phones while maintaining extended retention periods for video analytics and regulatory compliance. Moreover, developers now have the flexibility to configure fragment sizes based on their specific requirements — selecting smaller fragments for lower latency use cases or larger fragments to reduce ingestion costs. Both hot and warm storage tiers integrate seamlessly with Amazon Rekognition Video and Amazon SageMaker, enabling continuous data processing to support the creation of computer vision and video analytics applications.

Amazon Kinesis Video Streams with the new warm storage tier is available in all regions where Amazon Kinesis Video Streams is available, except the AWS GovCloud (US) Regions.
