Hi @RohithChippa,

Databricks Clean Rooms are designed to facilitate secure and privacy-safe collaboration between multiple parties on sensitive data. Here are the details your questions:

Environment Hosting: Databricks Clean Rooms are hosted by Databricks. When you create a clean room, it establishes a central clean room, which is an isolated ephemeral environment managed by Databricks.

Data Sharing: Participants share data assets through Delta Sharing. This allows collaborators to share tables, volumes, and notebooks with the central clean room without exposing the underlying raw data directly to each other.

Compute Resources: Notebooks in Databricks Clean Rooms are run using serverless compute. This means that the compute resources are managed by Databricks, and the collaborators do not need to manage the infrastructure themselves.

Billing Details:

Charges for Databricks Clean Rooms: The creator of the clean room incurs charges based on a per collaborator per day fee. For example, a 2-party clean room will incur a 50chargeper24hours,whilea3−partycleanroomwillbecharged50 charge per 24 hours, while a 3-party clean room will be charged50chargeper24hours,whilea3−partycleanroomwillbecharged100 per 24 hours

Compute, Storage, and Data Transfer Costs: In addition to the per collaborator fee, the clean room creator is also responsible for the costs associated with compute, storage, and data transfer usage within the clean room. Compute is billed using the “Jobs Serverless” SKU for AWS users and the “Automated Serverless Compute” SKU for Azure users. Storage is billed using the “Databricks Storage” SKU.
