Where can you host the SAP Ariba Integration Toolkit?

The correct option indicates that the SAP Ariba Integration Toolkit can be hosted on a customer standalone Windows server. This flexibility allows organizations that have their own IT infrastructure to implement the integration toolkit according to their specific needs and preferences. By hosting it on a standalone server, customers can manage security and compliance more effectively, as well as integrate the toolkit with their existing systems without being limited to a cloud-only solution.

The ability to host the toolkit on a standalone server is particularly beneficial for companies that have strict data governance and security requirements, or those who prefer on-premise solutions to maintain control over their IT environment. This choice avoids potential risks associated with data transmitted over public servers or cloud environments while providing the necessary capabilities to leverage Ariba's procurement functionalities within the customer’s systems.

The other options imply hosting restrictions that do not align with the actual capabilities of the integration toolkit.
