+Having a centralized log collection mechanism using kinesis firehose provides the following benefits:
 
-* helps to collect logs from different sources in one place. Even though the sample provided sends logs from Lambda, log routers like `Fluentbit` and `Firelens` can be used to send logs directly to kinesis firehose from container orchestrators like `EKS` and `ECS`.
-* define and standarize the transformations before the log gets delivered to downstream systems like S3, elastic search, redshift etc
-* provides a secure storage area for log data, before it gets written out to the disk. In the event of machine/application failure we still have access to the logs emitted from the source machine/application
