Overview

The Data Services Marketplace system consists of four Docker containers — the Marketplace Backend, the Marketplace Progressive Web App (PWA), the Database, and the Identity and Access Management (IAM) service — running on computing infrastructure managed by the Data Services Marketplace operator. This infrastructure may be hosted in the cloud or on private servers.

Although the Marketplace PWA is hosted by the operator, it is accessed from the user’s device; therefore, it is represented within the User Device box in the diagram. Furthermore, the Marketplace Backend may redirect certain requests to the eligible party’s service, which runs on the eligible party’s own system.

Node	Description
Operator Infrastructure	The computing infrastructure managed by the Data Services Marketplace operator that hosts the Marketplace Backend, Marketplace PWA, Database, and IAM. The actual deployment setup may vary depending on the operator’s environment. While the IAM typically maintains its own database, it can alternatively use the same database as the Marketplace Backend — provided that separate schemas are used to isolate their respective functionalities. The IAM may also be hosted independently by a third-party provider and does not necessarily need to be operated by the Marketplace operator.
User Device	Since the Data Services Marketplace is implemented as a Progressive Web App, the User Device can be any type of end-user device, such as a smartphone, laptop, or tablet. The PWA, running either as an installed app or directly in a browser, communicates with both the Marketplace Backend and IAM using HTTP requests.
