I'm trying to understand what On-Prem gateways do.
1) It would seem that in this context, "On-Prem" means "Behind the firewall." I would assume an On-Prem gateway isn't needed if the server was already accessible via the internet, whether it's on premises or not.
2) What does the Gateway do? I'd assume it uses something like reverse tunneling to allow acces to the Dataverse applications for servers that are behind a firewall?
3) What hardware/software is required? I'd assume the Gateway has to be installed on a Windows machine that's always on? If the data source is Linux, and there are no Windows machines, does that necessitate installing a Windows machine just to serve as the gateway?
Hi @oguruma ,
You have a few questions here 😀
1) It would seem that in this context, "On-Prem" means "Behind the firewall." I would assume an On-Prem gateway isn't needed if the server was already accessible via the internet, whether it's on premises or not.
The key thing here is that the gateway is the not directly internet accessible as you mentioned. The focus of this gateway is to allow "outbound" communication from within the on-premises (or wherever) environment when the server is not internet facing. This is definitely the case in situation like a database server which would normally never be internet facing. The advantage of how the gateway works is it is "outbound" only and does not require any inbound ports to be opened up. It will reach out, grab the command to execute, and then return the information requested.
2) What does the Gateway do? I'd assume it uses something like reverse tunneling to allow acces to the Dataverse applications for servers that are behind a firewall?
I think I answered this above. Let me know if it does not...
3) What hardware/software is required? I'd assume the Gateway has to be installed on a Windows machine that's always on? If the data source is Linux, and there are no Windows machines, does that necessitate installing a Windows machine just to serve as the gateway?
Gateway installation requirements are as defined: https://learn.microsoft.com/en-us/data-integration/gateway/service-gateway-install
If your environment is all Linux, as far as I know, yes, you need to have a Windows environment for this based on supported infrastructure.
