Answer: Data

In Databricks architecture, data is stored in the customer's own cloud account (AWS, Azure, or GCP) rather than in Databricks' infrastructure. This is a key security and compliance feature of Databricks' architecture. The Databricks web application, cluster management metadata, repos, and notebooks are typically stored in Databricks-managed infrastructure. This separation ensures that customers maintain full control over their data while leveraging Databricks' compute and management capabilities.
