Hi All,
I think I might be missing something in regard to No Pubic IP Clusters. I have set this option on a workspace (Azure) and setup the appropriate subnets. To my surprise, when I went to setup a JDBC connection to the cluster the JDBC connection string uses the workspace dns which resolves to a public IP address. The connection is successful.
I would have thought to access the databricks JDBC endpoint in this configuration I would need to access via the private network. Isn't this the point of No Public Cluster? If this is the only option, to allow JDBC into the cluster via the public workspace IP, how can I limit what can access this endpoint?
Regards,
Ashley

Hello @Ashley Betts
No Public IP means that the nodes/instances used in the cluster do not have a public address binding, rather only Private IP addresses. All traffic between Azure Data Plane and Databricks Control Plane will be routed through a secure ngrok relay which would otherwise require public internet access.
But the Webapp can still be accessible using public IP in this case
You have a couple of options to restrict such access
