Cloudera Platform Foundations

The Cloudera Platform domain tests your grasp of CDP architecture, deployment choices, core services, and administrative boundaries. Expect questions that distinguish control plane from data plane, match services to use cases, and identify which security and governance components apply in public versus private deployments.

Core architecture

  • CDP is a hybrid data platform built on open source. It separates the control plane (management, orchestration, and shared services in Cloudera's cloud) from the data plane (customer-managed cloud account or on-prem cluster). Your data stays in the data plane.
  • Deployment models: CDP Public Cloud on AWS, Azure, or GCP; CDP Private Cloud Base on bare metal or VMs with Cloudera Manager; and containerized CDP Private Cloud on OpenShift.
  • Data services are provisioned independently: Cloudera Data Warehouse (CDW), Cloudera Data Engineering (CDE), Cloudera Machine Learning (CML), Cloudera DataFlow (CDF), and Cloudera Stream Processing (CSP).
  • Cloudera Manager is the administrative console for Private Cloud Base; it manages roles, parcels, and health. In Public Cloud, the CDP control plane provisions services, and Cloudera Manager is not the primary user interface.
  • SDX (Shared Data Experience) provides shared security, governance, metadata, and lineage. In Public Cloud, a Data Lake service anchors SDX and hosts Ranger and Atlas.
  • Security: Kerberos or IDBroker for authentication, Ranger for authorization, Atlas for classification and lineage, Knox for gateway, and TLS for encryption in transit.

Worked example

A bank wants on-prem Spark ETL and cloud BI with one set of authorization policies. Which element gives consistency? SDX. Reasoning: SDX centralizes Ranger policies and Atlas metadata so CDW and CDE in the cloud and Private Cloud Base clusters enforce the same tags and rules. Cloudera Manager only manages a cluster; the control plane orchestrates services; policy consistency comes from SDX.

Traps

  • Equating Cloudera Manager with the CDP control plane. Manager is for Private Cloud Base clusters; Public Cloud uses the control plane.
  • Assuming every data service is available in every deployment model with identical sizing.
  • Forgetting that the data plane runs in the customer's account or network; Cloudera does not store your data.
  • Treating SDX as a product rather than a set of shared services.
  • Overlooking that containerized Private Cloud uses Kubernetes and Cloudera Data Services, not Cloudera Manager for service provisioning.
