Hi @dmharshit
As you know, Cloudera provides the Hybrid data platform, so you can install the CDP product in on-premises and public cloud or both.
CDP Private Cloud Base product is supported only for On-Premises cluster.
CDP Public Cloud Base product is supported for public cloud like AWS, Azure, GCP.
@fzsombor already shared references how you can install CDP Private cloud and how to install Spark3 as well.
Please let me know still you need any further information.
