Hi @noorbasha534,

Does this control plane then contains management services for several customers? - Yes, Control Plane has management services that are used across customers in the region. 

Due to which the presenter says traffic can be isolated from traffic of other customers...? - Yes, When using private link, the traffic will go through the private tunnel as mentioned in the video. Here, "isolated" doesn't mean that the control plane services will not be shared but it means that it would skip public internet and hence workloads, data etc will remain isolated.

Do let me know if you need any inform on this.
