Self-service data platform based on the data mesh principles

Wants to build a self-service data platform based on the data mesh principles with providing data as products. The
“Customer” data product is central in this work and currently the customer data is kept in SAP CRM.

You have to use GCP for this task.
• How would you proceed with the assignment to build the “Customer” data product?
• Provide a high-level architecture diagram as basis for explaining choices made

I need a detailed documentation on the above 2 points.
A clear high level diagram with explanation how and why to use certain parts of GCP for the proposed solution.

Any question please contact.
