Data Product Hub is hosted as a secure multi-tenant solution. Multi-tenant databases are used for all metadata storage in Data Product Hub. For data products, the metadata about the data source is collected and stored in the multi-tenant databases. Customer-owned data is not copied or moved from the source location.
Data Product Hub is deployed in the Dallas (us-south) region.
Uploaded PDF files for data contracts, data profile information, and project system data are stored in the Cloud Object Storage instance that is provisioned and owned by the customer. See Managing security and compliance with IBM Cloud Object Storage for deployment models for Cloud Object Storage.
Delivery methods and data isolation
-
Open URL or Download: When data items are accessed by using the Open URL and Download delivery methods, source data does not flow through Data Product Hub. Customers receive a link to access content or download files directly from the source.
-
The Flight service: For the Flight service delivery method, consumers receive a code snippet to connect to a specific data asset using the Flight service. Data moves through the Flight service data plane on the solution to the user's application. Data access through the Flight service depends on both the source access controls and the connection credentials in Data Product Hub. The connection that is used for Flight service delivery must be configured with read-only credentials.
-
Download data extract: Download data extract has two stages for moving data. The first stage is extracting the data and generating a CSV file. A Data Refinery job copies data from the source system to the target system. Data flows through the Analytics engine on the data plane. The second stage is downloading the extracted CSV file. Data flows directly from the target system to the consumer and does not move through Data Product Hub.
