Hi Communities,

Just wanted to explore on if there is any alternative approach to Grafana PDC available? We do have some security concerns around opening port 22 from PDC Agent to PDC Service.

We’ve our datasource on Prem and we do want to leverage Grafana SaaS for the dashboarding purpose only.

Alternative is to expose your on prem datasources on the Internet, so Grafana SaaS can connect to them directly.
I guess you will know that this is less secure alternative than PDC.

I would say that ssh tunnelling is standard secure way. What are yours security concerns for this concept?
