It's great to see Microsoft introduced on-premises data gateway for providing a quick and secure connection between on premise data and Office 365 apps. This has quenched the intellectual thirst of Office 365 customers for their long wait for connecting on premise data to Office 365 apps.

Now as I see in the forums many of the Office 365 customers and technology enthusiasts has questions that they are looking for answers. Below are the some of the FAQs I have noticed in discussions.

For deployment of on-premises data gateway and connecting on premise data to Office 365 apps with screenshots, refer these blogs - Deployment of On-premises data gateway , Connect on premise data to Office 365 apps.

1. How many gateways can be deployed in each on premise machine?

You can deploy only a single gateway

2. Whether any additional configuration required for SharePoint 2016/SQL 2016 during gateway deployment?

No, there is no additional configuration required for SharePoint 2016/SQL 2016 during gateway deployment.

Yes, but you will receive the following error,
"Error generating an asymmetric key.
The requested operation cannot be completed. The computer must be trusted for delegation and the current user account must be configured to allow delegation."

To fix the above error, open Services console, select On-premises data gateway service change the service account from NT SERVICE\PBIEgwService to Local System and restart the service.

10. Whether connection added in any one of the Office 365 apps will be available for access to all other apps?
