Study Notes

Databricks Workspace Architecture

Databricks Workspace is a serverless application hosted in the Azure cloud.
The workspace is accessed through a web UI (URL).
It consists of two planes: Control Plane and Data Plane.

Control Plane

Databricks software (serverless application) resides in the Control Plane.
It includes:
- Databricks web application (accessed through the web UI)
- Notebooks created within the workspace
- Job configurations, queries, alerts
- Cluster configurations
The Control Plane is managed by Databricks and not directly accessible by users.
Users interact with the Control Plane through:
- Web UI
- REST-based APIs
- Command line tools

Data Plane

Resides within the customer's Azure subscription, implying full control and responsibility.
Includes:
- Databricks clusters (virtual machines)
- Data storage layers (e.g., Workspace root storage (DBFS) and custom data storage accounts)
Users are responsible for managing and paying for resources within the Data Plane.

Data Storage

Workspace root storage (DBFS) is the default storage layer for a Databricks workspace.
DBFS is created within the Data Plane and is secured by Databricks.
It is generally not recommended for storing large data volumes or for data ingestion.
For production environments, a separate data storage account within the Azure subscription is typically used for data ingestion and management.

Important Points

The Control Plane manages all configurations and functionalities of the Databricks workspace.
The Data Plane hosts the compute infrastructure and data storage, allowing user control and responsible for costs.
