Amazon Kinesis Data Streams now supports resource-based policies, so you can process data ingested into a stream in one account with an AWS Lambda function in another account. Amazon Kinesis Data Streams is a serverless real-time data streaming service that can continuously capture gigabytes of data per second from hundreds of thousands of sources. AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers. Together with Kinesis Data Streams and Lambda, you can build a completely serverless data streaming pipeline.
