Quick Note. We have built a collectord (container-native log forwarding tool), that is compatible with AWS Services, including AWS S3 + Athena + Glue (partitioned in Hive compatible format).
With this, you can significantly reduce price for the log aggregation tools and keep much longer retention for the logs.
We actually have built a calculator, that can help you to estimate the cost of using AWS Services with Collectord for managing Kubernetes and Docker logs.
