Apache Hadoop HDFS vs Apache Ozone

Both stand on data lake software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Apache Hadoop HDFS

Free plan Open source APILinuxSelf-hosted+1

HDFS is built for distributed, high-throughput storage with replication and several access interfaces. Its write model and security requirements should fit the workload and deployment plan.
