Kinesis Data Firehose
No application template
Kinesis Data Firehose has no application template. In practice Firehose delivers to an S3 bucket, which is then read through the S3 notification path. See the Integration Matrix for which products use which path.
Fluency offers several CloudFormation scripts to facilitate integration. While these scripts are free to use, keep in mind that AWS CloudFormation is a paid service, and you will incur a charge from AWS for using it.
AWS CloudFormation allows you to configure AWS resources from script/code. This makes deployment easy, consistent, and greately decreases the possiblity of errors or misconfigurations.
For supported AWS integrations, deploying via CloudFormation is always recommended, if the script is avaliable.
