Select the source for your data stream, such as a topic in Amazon Managed Streaming for Kafka (MSK), a stream in Kinesis Data Streams, or write data using the Firehose Direct PUT API. Amazon Data Firehose is integrated into 20+ AWS services, so you can set up a stream from sources such as Databases (preview), Amazon CloudWatch Logs, AWS WAF web ACL logs, AWS Network Firewall Logs, Amazon SNS, or AWS IoT.
