How to add Web Source to Power BI Cluster?

Hi AlbertoPinon ,

While cloud data sources don't necessarily require a gateway, a gateway is required if a dataset connects to both on-premises and cloud sources in a single mashup query. In this scenario, Power BI must use a gateway for the cloud data sources as well.

For more details,please refer to:
