Amazon Kinesis Data Streams is a serverless streaming data service that makes it easy to capture, process, and store data streams at any scale. On-demand streams automatically increase ingest capacity in response to rising data ingest usage. With On-demand Advantage mode, you can proactively manage stream capacity using warm throughput to prepare streams for sudden changes in data traffic. We are extending warm throughput with the ability to also scale down ingest capacity, giving you full control to scale your stream’s write throughput up or down.

To scale down, simply set a lower warm throughput value on your on-demand stream. The stream adjusts to the requested capacity or the amount needed to support peak data ingest usage in the last hour, whichever is higher. This ensures your stream always retains sufficient capacity for current traffic while releasing excess capacity you no longer need. As a result, you get optimal stream-processing performance and cost efficiency. 

Warm throughput scale-down is available at no additional cost for all on-demand streams with On-demand Advantage mode enabled.  For more information about On-demand Advantage, see Choose the right mode to stream in in the Amazon Kinesis Data Streams Developer Guide. To get started with the feature, see Update a stream. For pricing details, see Amazon Kinesis Data Streams pricing.

The feature is available in all AWS Regions where Amazon Kinesis Data Streams On-demand Advantage is supported.

AWS Lambda now publishes logs for Lambda Managed Instances (LMI) capacity providers to Amazon CloudWatch Logs, giving you visibility into scaling activity and instance lifecycle operations. LMI enables you to run Lambda functions on Amazon EC2 instances while maintaining serverless operational simplicity. Capacity providers are resources that let you define compute resources that Lambda provisions on your behalf. With capacity provider logs, you can monitor, troubleshoot, and optimize these managed EC2 instances, helping you quickly diagnose provisioning issues and understand scaling behavior.

Customers use LMI to operate high-volume, predictable workloads with specialized compute configurations and achieve cost efficiency through EC2 pricing options like Savings Plans and Reserved Instances. With this launch, Lambda automatically generates logs for compute resources managed by capacity providers and delivers them to CloudWatch Logs. Lambda publishes structured JSON logs capturing instance lifecycle events like launches, terminations, and health checks. This structured format lets you identify failed operations and provisioning errors through CloudWatch Logs filtering, helping you resolve issues quickly and shorten debugging cycles.

The capacity provider logs are available in all AWS Commercial Regions where LMI is available. The logs are enabled by default for all capacity providers. You can view your capacity provider logs by visiting the Lambda console’s capacity provider page. You can use the Lambda API, Lambda console, AWS CLI, AWS SAM, or AWS CloudFormation to change capacity provider log configuration. Standard Amazon CloudWatch Logs charges apply. To learn more, visit the AWS Lambda Managed Instances product page and documentation.

Today, AWS announces a research preview of aws-bench, an open-source benchmark that measures how accurately and efficiently AI agents complete real-world AWS tasks. Model providers and AI researchers building agents that operate on AWS infrastructure need an objective, reproducible way to measure performance and diagnose failures. aws-bench provides a public suite of test cases derived from analysis of real AWS usage, including investigation, troubleshooting, and infrastructure creation tasks.

Each test case pairs a natural-language query with a defined cloud resource state and a ground-truth answer, so you can score any agent or model on a consistent, verifiable basis. Researchers and model providers can use aws-bench to improve foundation model performance on AWS tasks, improve agent harnesses, and track improvement progress. The release includes an easy-to-use CLI tool to instantiate testing environments, execute and score evaluation runs, and reset resource state.

aws-bench is available now on GitHub. To get started, follow the setup instructions on the README.
